Among the marine aquifer animals there is one of the most beautiful species, the blue whale, which is also called the blue whale, is gigantic, if you join this wonderful tour you will discover its characteristics, such as its behavior, its diet and everything related to its life in the sea.
How is the Blue Whale?
It is a mysticete cetacean that instead of having teeth has a graceful beard, Balaenopteridae is its family of origin, it has been recognized as the most impressive sperm whale on the planet, reaching 30 meters in length, weighing 180 tons, it is charming as the Gray whale appreciating its beauty is the most valuable thing that human beings can treasure.
The blue whale is better known as the blue whale, despite the fact that its scientific name is balaenoptera musculus of the balaenopteridae family, in medium size it can be achieved in measures between 24 and 27 meters long with weights of up to 100 and 120 tons. Which implies that they have become the most gigantic animal in the world.
What can be mentioned as a curious fact is that his tongue weighs as much as an elephant would and his heart weighs as much as a vehicle, it is really amazing, his body is marvelous to observe because it is finely stylized and very long of a bluish gray color. the entire part of the back and that when going down to the ventral area it becomes lighter blue.

Of the blue whale, three very different subspecies are known: the Balaenoptera musculus musculus, which is located in the Pacific and North Atlantic regions, the Balaenoptera musculus intermedia, which is found in the Antarctic Ocean, and the Balaenoptera musculus brevicauda, which is called the pygmy blue whale. very typical of the areas of the Indian Ocean and the South Pacific.
The charming whale, like other baleen whales, feeds on very small crustaceans called Krill, this beauty was abundant in most of the Oceans until the beginning of the 40th century, for more than 1.966 years they were persecuted by the fearsome whale hunters until they almost disappeared, it was From there, the idea of protecting them through the international community arose in XNUMX.
According to the records of the year 2002, an estimate was made of some 5.000 and 12.000 individuals throughout the planet earth, distributed in only about five groups, agreeing on an estimate
Everything happens long before the famous commercial whaling began, considering that the largest whaling population was in Antarctica with a population of 239.000, which currently has a population of 2000 individuals, which is much lower in the Indian, Antarctic and Northeastern Pacific Oceans, with two groups distributed in the North Atlantic and at least two in the areas of the southern hemisphere.
Distribution of the blue whale-Cetacea that fascinate
How interesting it is to know that it is cosmopolitan, it implies that it is distributed in all areas of the planet with the exception of the Arctic, just as it is not possible to obtain it in seas such as the Okhotsk, the Mediterranean or the Bering seas, it loves the continental platforms so much like open ice fields.
Likewise, it has been discovered that they have been found in very deep seas, which currently indicates that they are seen in the North Pacific and that the North Antarctic is where the largest population of blue whales really concentrates, just as it does the polar bear an animal also majestic.
Taxonomy
The most disciplined way to organize this incredible and graceful swimmer is to locate it as would be done with all mysticetes referring to whales of the Balaenidae family and that the fin whales refer to the Balaenopteridae family that has among its conformation the blue whale, the fin whale, the humpback whale, the boreal whale, bryde's whale, minke whale, austral whale, omura whale and tropical whale.
It is quite credible that the family balaenoptiridae differed from other classes of the suborder mysticeti in the middle Oligocene, added to this, there is no precision of the separation between them.
The blue whale is only distinguished as one of the eight rorqual species in the balaenoptera classification, even though it was classified in accordance with the authority that thus designated it to be of the genus Sibbaldus, it was not established until they emphasized the sequencing of DNA where it is indicated that it is phylogenetically more closely linked to the minke whale- Balaenoptera boraelis.
As well as the genus bryde-balaenoptera brydei, like the other balaenoptera individuals, much closer to the yubarta-magaptera, to the gray whale-eschrichtius, than to the minke whales-balaenoptera acutorostrata and the austral whale-balaenoptera bonaerensis until today.
Therefore, it is worth mentioning that there are cases of hybrids that have been documented between this species and the typical whales in the natural environment, although it is not known how much reproductive capacity they have, considering what was said by Gullberg and Arnason who established a genetic distance between the fin whale and the blue whale as similar as that between the gorilla and the human being.
Therefore, it is of interest that the name of the species, musculus, originates from Latin, implying that it refers to muscle, it was Linnaeus who called it a blue whale in his system naturae of the year 1.758. In other times it was determined by other names such as Sibbald's whale in honor of Sir Robert Sibbald, enormous blue whale and immense northern whale, which were names that were left behind.
Four subspecies also emerged, but one of them is not certain:
- Balaenoptera-m-musculus by Linnaeus in the year 1.758 which referred to the blue whale including the North Pacific and North Atlantic populations.
- Balaenoptera-m-intermediate by Burmeister in the year 1.871, as the Antarctic blue whale, the largest and that can be located in the Antarctic Ocean.
- Balaenoptera -m -brevicauda by Ichihara in 1.966, the pygmy blue whale with individuals in the South Pacific and the Indian Ocean.
- And the Balaenoptera -m-indica of doubtful origin by Blyth in 1.859, the great whale of India, which is obtained in the Indian Ocean and which may be the same Balaenoptera -m- brevicauda.
Description and behavior of the Blue Whale
Due to its enormous size, it has been described that the blue whale reaches amazing speeds of up to 50 km/h when, by natural instinct, it feels that there are threats surrounding it, they generally move at 22 km/h and when they feed, that speed drops to 5 or 6 Km/h, she can reach depths of up to 100 and 500 meters.
The most incredible thing is that it can stay underwater for more than 10 and up to 20 minutes, then it comes to the surface to launch a jet of steam that manages to capture the gaze from several meters away, reaching heights ranging from 6 to 12 meters. , has an excellent lung capacity of 5.000 litres.
It has a very slender and long body that seems very fine compared to the plumper constitution of other mysticetes, it has a huge head that is a quarter of its body, being also very flat in the shape of a U carrying a crest that comes out from the spiracles towards the anterior side of its face.
The mouth in its front part is very thick, it has between 300 and 400 beards on each of its sides, in which each of the beards have a length of approximately 1 meter to hang over its upper jaw, they are 50 centimeters wide. relative to its length.
It has grooves that go from 55 to 88, which are usually called ventral folds that appreciate the extension of the throat, they are very parallel to the body, they are the ones that allow the exit of water through its mouth, after the lunges to eat.
The amazing dorsal fin can only be seen by diving into the sea, it is a fin that is located at the beginning of the last quarter of the body, quite small and very variable, it can be round, triangular, delicately curved or a small dent.
It is wonderful to appreciate at the moment when it comes to the surface to look for air, right there, it exhibits its back and its spiracle out of the water much more than other baleen whales such as the typical or the minke whale, these are aspects that observers use to distinguish them. at sea.
Long before starting a pirouette to go deep, they show their fin out of the water to show it off, a very striking event that they do when breathing on the surface.
It has been very original in baleen whales that have a double spiracle, which is well protected by a protuberance from the front to the side, more safely than other whales. They are pectoral fins with a pointed shape that measure between 3 and 4 meters, gray with a delicate white stripe on the upper tip and white on the lower part.
The head and the caudal fin are shown in gray, which is often mottled in the upper region and occasionally the fins, it is a blue whale feature very variable because hundreds of them can be all completely slate gray, while others can be dark blue, black and gray all with tiny spots scattered throughout their body.
Its belly area is usually shown in a yellowish or grayish color because it rubs a lot with the animals called diatoms that are found in the coldest waters of the Antarctic, the North Atlantic and the North Pacific, they are so fast that they manage to reach a speed of 50Km/h, that is to say 27 knots when they feel that they are being threatened.
The normal speed that the blue whale travels is only 22Km/h, that is, 12 knots of displacement, while if they feed they reach a speed of 2 and 6,5 Km/h, 1 and 3,5 knots, they like live in pairs or alone, it is very important that they group with up to 7 individuals to eat where they get food, so that up to 60 whales can be grouped in the same place to eat.
Even when they are grouped, they are not comparable like the other groups of baleen whales, taking into account that DNA analysis indicated that blue whale pairs when they are adults are made up of a female and a male, but that they have also been seen for a long time to certain males mating with totally different females.
Size and mass of the blue whale
Motivated by their enormous size, weighing them is not at all easy, since time immemorial when the blue whale was hunted, they did not weigh them whole, they only did it by parts of cuts that they made and that they considered were better to handle, which caused a lot of controversy because by doing it that way there was loss of blood and certain fluids.
But, even so, it can be seen that an adult individual can measure between 24 and 27 meters in length, weighing between 100 and 120 tons, the largest of which is recorded as measuring 33,63 meters when the valid measurement and certified was 29,9 meters.
In the South of Georgia in the year 1.947, a female blue whale weighing 173 tons was captured. Special consideration is given to the fact that those in the waters of the southern hemisphere are much larger than those in the north and that the females are more gigantic than the males.
The blue whale has been estimated as the most massive animal in existence on the entire planet earth above any other animal in weight that is present or has existed, the blue whale being in a great way hyper heavy more than the already extinct known patagotitan mayorum Like the aquatic dinosaurs more gigantic it was 77 tons in mass.
The extinct fish Leedsichthys very similar in size, noting that it was not an easy task to get the complete fossils and that only the weight was estimated and even so they were not as prominent as the blue whale.
What an amazing surprise that the lenga of this beautiful animal has a weight of 2,7 tons and even more amazing when it is opened that it can store up to 90 tons of food and water. Incredible that being so big it can't swallow objects that are bigger than a beach ball.
The heart of this beautiful whale is so huge that it weighs 600 kg, which means that it is the largest in terms of an animal, in addition to having its aortic vein with 23 centimeters in diameter, another thing is that the blue whale when born it weighs up to 2.700 kg and measures 7 and 8 meters equal to an adult hippopotamus.
Food
The question arises, what do whales eat?; they eat Krill, which is a food in the order of crustaceans, they can consume up to 40 million of them daily and once its jaw closes it expels the excess water while it retains the food with its baleen, it also feeds on tiny minnows, squid and many other crustaceans.
They are such a special species that they only need 1,5 million calories a day, which is what will allow them to have a sufficient amount of vigor and therefore help them to be very active.
It is interesting to understand that even when they feed on Krill they also eat very small amounts of copepods, which is a species from which the zooplankton comes from, from which they eat many that go from one Ocean to another, as in the North Atlantic they get the Thysanoessa inermis, Thysanoessa raschii, the meganyctiphanes novergica.
Very diverse species, Thysanoessa longicaudata their favorite dish, having in the North Pacific region Thysanoessa spinifera, Thysanoessa raschii, Euphausia pacifica and Nyctiphanes symplex, observing in the Antarctic Euphausia Valentín, Euphausia superba, Euphausia crystallorophias species that serve as food for this great whale.
It is impressive to know that an adult whale eats up to 40 million Krill daily, which is why they go to the most populated areas with these crustaceans, eating up to an estimated 4 tons per day in the peak season and perhaps up to 8 tons because they require of a lot of caloric energy per day.
For the most typical thing when they eat they do it at a depth of more than 100 meters during the day and at night they only do it on the surface, in the deep it is in a period of time that goes from 5 to 15 minutes, even when They have been recorded in dives of up to 20 minutes which is the most common and up to 36 minutes, they have an excellently amazing lung capacity.
The most curious thing is when they feed, it is an event that they carry out through the filtering system, it is the so-called lunge when it opens its mouth filling it with a large amount of water and many Krill, then it closes its jaw by pushing the water up to pull it out through their beards.
This helps the water to be expelled while it hunts its prey retained in them; they are very beautiful when they perform these events that are part of their life in the sea, seeing them submerge and then come to the surface is fantastic, it is unique, it is special to appreciate moments like that.
Reproduction of the Blue Whale
The time at which the blue whale reaches sexual maturity is between five and ten years of age, indicating how whales are bornThey have a gestation period that takes approximately 10 to 12 months, it is a process that the female blue whale lives and usually gives birth to a single calf every two or three years and that is born in the winter season in very fresh waters with low altitudes.
It is a calf that is born weighing about three tons, measuring between 7 and 8 meters long, very curious what are the measurements and weight of an adult hippopotamus, the calves suckle for 8 months, the blue whale has a great life expectancy of 80 and 90 years.
Life cycle
The moment to mate arises precisely between the autumn season and continues until the end of winter. There is not much information on how this behavior is or how it is coupled to have its offspring, which give birth in the winter season, a very cool season.
It is a baby that weighs about three tons and that measures between 7 and 8 meters long, they are calves that drink a lot of milk a day about 380 liters, to increase about 90 kg of weight per day, weaning happens when they are already 8 months old old, it is a time when the calf has grown double.
The males reach sexual maturity at 5 years of age, just when they measure 20 and 21 meters long and for the females when they reach 21 and 23 meters, just like the males at 5 years old, it can be understood that physical maturity in males that are located in the northern hemisphere it occurs when they reach 24 meters in length and in females when they reach 25 meters in length, they live for more than 80 years and even more.
It can also be noted that the strandings of these animals on the coasts are not very regular, due to the species in its social structure, so seeing massive strandings is something amazing that when it happens they attract a lot of people's attention.
Once an event occurred that was very interesting in the year 1.920 when an individual whale got stuck very close to Bragar on the little island of Lewis in the Outer Hebrides of Scotland, there a whaler's ship stuck a harpoon into it, which did not It exploded allowing the whale to end up on the coast, where two of its bones were carved there in Lewis and which to this day are an attraction for tourism.
Vocalization
It is very interesting to know that the blue whale has such an extraordinary vocalization that those tremendous sounds that it emits are incredibly low with a frequency very suitable for establishing long-range underwater communication.
Said by Cummings and Thompson who managed to make an estimate in the year 1.971 of a volume of 155 and 188 decibels relative to a micro Pascal (µPa) of a distance of one meter. It is considerable that all the groups launch calls at a frequency of 10 and 40 Hz and can even reach 9 Hz, taking into account that the lowest sound that the human being can capture is 20 Hz and the highest reaches 524 Hz
They are emissions of calls that last between 10 and 30 seconds, for example, in Sri Lanka they managed to keep records of these songs that made up four notes that lasted two minutes each, emitting the delicate songs of the humpback whales.
But researchers have considered that this is a phenomenon that has only been discovered in the subspecies of Balaenoptera musculus brevicauda-pygmy. It is not known for sure why they emit this kind of sounds, although Richardson et al described in 1.995 that there were six possible reasons:
- The conservation of the interindividual distance.
- The recognition of the species and its individualism.
- The communication between them in allusion to food, courtship and state of alarm.
- Conservation of social groups in relation to calls between females and males.
- Situation of topographic features.
- The position of prey in sight.
Population and hunting
The decline in population and the indiscriminate hunting of these impressive whales is a matter of concern in countries like Japan, Norway and Iceland, because other problems are also added, such as the destruction of their habitat, climate change and pollution, and there is not much that can be done to protect this species.
For about 40 years, the issue of raising awareness in the world about hunting has been addressed in such a terrible way that it has been seen that they have done it, because they were persecuting it from new species as they were reduced, which is why Greenpeace has launched orientation with issues of protection and care.
And for the year 1.982, it managed to ban commercial whaling in countries that were part of the International Whaling Commission-CBI, due to massive social pressure and the sad condition in which these mammals were found.
Spain was a country that hunted these whales until the time this whale protection precept was issued. It was something that was established from the year 1.986 and there is even talk of a Greenpeace Rainbow Warrior I ship that was stopped at the station in Ferrol by the soldiers of the Spanish Navy precisely for presenting resistance to the Galician whalers. And in the year 1.994, a Whale Sanctuary was created by the IWC itself in Antarctica.
The decades of hunting
These decades are imperative because whales are not at all easy to hunt or kill, they very rarely remained in the sights of the first whaling ships because their size, speed and enormous strength was a very important factor in preserving their lives.
Only right whales and calves were hunted. By the years of 1.864 it was established that the Norwegian Sven Foyn had armed a steamboat with the weapons that they had designed and prepared to hunt the largest cetaceans, they were difficult to work with and did not have any favors.
So Foyn was in charge of perfecting the harpoon gun with which later many whaling stations were established on the coasts of Finnmark, in the northern region of Norway. However, there were many discrepancies between the local fishermen, so much so that the last station was closed in the year 1.904.
With the entry of steam factory ships with stern ramps in 1.925, there was a great increase in blue whale hunting in a very drastic way because between 1.930 and 1.931 those ships hunted 29.400 individuals nothing more in the Antarctic region.
And only towards the end of the Second World War and the population had been quite reduced, so in the year 1.946 the first guidelines were given that limited the foreign trade of this species, not making much emphasis because it was not so accurate anymore. They did not establish any contrast between the species.
Pretending to hunt any of the species, it only mattered that there was a large population, until the year 1.960, when hunting was restricted by the International Whaling Commission, thus stopping the illegal hunting of whales by the Soviet Union in the year of 1.970.
It was a season where 330.000 blue whales were hunted in the Antarctic area, 33.000 in the southern hemisphere, 7.000 in the Atlantic and 8.200 in the North Pacific, so it was found that the largest group was from the Antarctic that was reduced to 0,15% of what it was at the beginning.
It is impressive how the whaling ships almost completely extinguished this species, because instead of hunting fewer whales in abundance, what they did was reduce it, they did not take into account that, if they had had the regulation and supervised guidance of biologists marine, more whales could have been made commercially available, just over a longer period of time.
Everything was framed in that due to the long periods of reproduction that took approximately one year of gestation with litters of one or two pups, they were ideal, because they recovered more slowly than the populations of smaller animals. Investing in it less time and resources in the younger species.
Current population and distribution
Determining the degree of the existing population of blue whales has not been so simple, since, from the moment the restriction for whaling was established, it has not been possible to obtain a study that, of veracity with respect to the global level of protection, it was only possible to verify that in the Antarctic region there was only an increase of 7,3% per year.
For this reason, it has been estimated that the total world population has been between 5.000 and 12.000 individuals in the year 2.002, since the IUCN red list was established, the blue whale has been in danger of extinction, the highest concentration of population is It is found in the North Pacific with about 2.000. It is a subspecies that ranges from Alaska to Costa Rica and can only be seen in the summer season from California.
On some occasions these individuals move towards the northwestern Pacific Ocean, registering very little between the Kamchatka peninsula and the north side of Japan. Locating only two groups of the blue whale in the North Atlantic.
For the greats of science, it is a mystery because they have not yet determined precisely where the blue whale spends its winter, so it is considered that this population in the North Atlantic was between 600 and 1.500 individuals.
Very emphatic the studies carried out in the southern hemisphere where it was believed to find the existence of two different subspecies, the Antarctic blue whale - Balaenoptera musculus intermedia and the little mentioned pygmy blue whale - Balaenoptera musculus brevicauda, well known in the waters of the Indian Ocean.
Surveys that were done in 1996 brought back about 424 minke whales in just a small region south of Madagascar, so examples in the entire Indian Ocean are likely to be a few thousand.
If this is valid, world populations would be higher than those provided by the introductory figures. The recent ongoing survey in mid-1998 returned a metre-2.280 individuals in the Southern Ocean, of which less than 1% were probably dwarf blue whales.
A fourth subspecies, Balaenoptera musculus indica, was represented by Blyth in 1859 in the North Indian Ocean, however challenges in distinguishing particular highlights of this subspecies make it a fairly similar word to Balaenoptera musculus brevicauda which is the dwarf blue whale.
Much of the data from the Soviets seems to show that the size of adult females is closer to that of dwarf whales than that of Balaenoptera musculus musculus, despite the fact that the populations of Balaenoptera musculus indica and Balaenoptera musculus Brevicauda have all the characteristics of be extraordinary and the breeding seasons vary around half a year.
The transitory courses of these subspecies are not yet remarkable. For example, there are records of minke whales in the North Indian Ocean from Oman, Sri Lanka, Maldives, where they may frame a native population.
On the other hand, the number of populations of blue whales found in Peru and Chile may also be an alternative population. Any of the Antarctic blue whales come to the eastern coast of the South Atlantic in winter, and their calls are infrequently heard in the northern Indian Ocean, Peru, and in western Australia.
In Chile, for example, the Cetacean Conservation Center, with the help of the Chilean Navy, attempted to carry out an important work of assessment and protection and is dealing with the investigation of a recent grouping of examples of care on the coasts of the Big Island of Chiloé in Chile. A region called the Gulf of Corcovado, where 326 creatures have been located near the coast in late spring and early summer in 2007.
Researchers at Duke University are making efforts to make increasingly accurate estimates of their population, which are maintained by OBIS-SEAMAP, Ocean Biogeographic Information System - Spatial Ecological Analysis of Megavertebrate Populations - Spatial Biogeographic Information System. Megavertebrate Population), a compilation of information on marine mammals from approximately 130 sources.
different dangers
Because of their gigantic size, speed, and strength, adults have virtually no characteristic predators. The main threat known to be the executioner whale is the killer whale. There are recorded reports of invasions of these creatures, for example, an investigation that showed that in the Sea of Cortez no less than 25% of individuals who are adults had scars due to attacks on killer whales and the disappearance of an individual in Baja California that was attacked.
Just like a report in National Geographic magazine of an adult being assaulted by orca whales where, even though the orca whales were unable to kill the creature during their assault, they sustained many injuries and died as a result of those attacks. The most frightening thing these whales can experience in a lethal way are collisions with huge ships in the high oceans and also getting caught in fishing nets.
The persistent increase in commotion encompassing man at sea, including sonar, overwhelms the vocalizations emitted by cetaceans, making communicational correspondence difficult. The human dangers for the expected recovery of its population also include the aggregation of polychlorinated biphenyls -PCBs and the different synthetic substances that they ingest when they eat and that are transmitted through mother's milk to their young.
Dangerous atmospheric devastation causes ice masses and permafrost to dissolve rapidly, causing a large increase in the extent of new water in the seas, and there is a danger of reaching a baseline in that expansion that could cause a disruption in thermohaline flow.
Like most cetaceans, blue whales are transient, spending late spring in higher, cooler ranges, where they feed in waters rich in krill; in winter they move to lower and warmer areas, where they mate and conceive an offspring.
Since their transient patterns depend on sea temperature, an adjustment to this course by uprooting hot and cold water far and wide would likely affect their relocation. The adjustment in sea temperature would also influence their food, thanks to warming causing a drop in salinity levels that would cause a big change in the status and richness of the krill.
Whales are paradisiacal species for their enormous size, for being calm, disconcerting and for their long transient excursions, a significant number of which are longer than other well-evolved whales on Earth. Whales are the celebrities of the ocean and a symbol of the battle to secure the planet.
The commercial hunting of whales led in the XNUMXth century, because oils and different products were obtained from them. It is in the XNUMXth century, where the use of innovation and popular expansion outpaced the whales as far as possible, endangering their populations.
Currently Spain is a member of the CBI within the European Union, which implies that the situation of the nation is exceptionally impartial. By not having commercial interests, they would not be campaigning for whaling, but neither would they be fighting for this slaughter to end once and for all.
What solutions are there?
The global agreement is to end any type of whaling business and make marine sanctuaries. Likewise, efforts must be made to fight against environmental change, pollution and overfishing, which also influence them.
Those in charge can help protect these huge marine species by supporting the IWC in its protection efforts, speaking out to whaling nations, being more proactive at IWC meetings, and avoiding the whale meat section of their ports.
Similarly, in the financial circle, whales and the travel industry created around them, for example, whale watching, have earned one of the largest monetary stipends in numerous nations and produce more prominent financial advantages than whale hunting for capture.
For example, in Iceland, even though they chase whales, they still manage to watch whales as an attraction. In the year of 2012, there was a recorded sighting of 175,000 individuals who went to see the whales swimming uninhibited in this nation, producing a greater number of advantages than whaling.
What is Greenpeace doing?
Greenpeace is fighting to end commercial whaling and persecution for supposedly logical purposes. The association needs the IWC to become a preservation organization for these huge mammals and take responsibility for securing and building marine sanctuaries for the whales.
In Japan, the association works reliably to increase buyer attention so that they do not accept whale meat. Greenpeace recognizes that it means to persecute, in light of the fact that it is unique in relation to commercial whaling. Additionally, the targets of this native persecution include:
- Ensuring that the dangers of slaughter do not expand on a large scale.
- Consent permanent captures that adjust to social and healthy needs.
- Maintain populations with organically compatible rates of multiplication.
Under current IWC guidelines, resource seeking is permitted for the Aboriginal group in Denmark, the Russian Federation, Saint Vincent and the Grenadines, and the United States. It is the duty of each government to provide the Commission with evidence of the social needs and resources of their families. The Scientific Committee advises on the protected capture cut-off points of these populations.
Blue whale predators
The main sea creature that will generally attack the blue whale is the killer whale, however, as it is an extremely large cetacean, it likes to take on calves or worn-out old ones. The blue whale is an endangered species due to some components.
Among them is the disappearance of some individuals due to injuries caused by huge boats or by being trapped in fishing nets. Consequently, a global change in temperature has caused the maritime oceans to change their temperature and consequently, the abundance of krill and the different fundamental species for the whale begins to be in danger.
At this time, the pursuit of blue whales has been punished on any land mass since the year of 1966, despite the fact that it is realized that this is not constantly considered by the gatherings of illegal trackers around the world that exploit different pieces of its vital structures. The Red List of the International Union for Conservation of Nature characterizes the blue whale as an endangered species.
