Know the types of marine corals and find out more about the aquatic world and its kingdom. The animals of the water world have amazing characteristics, their appearance, anatomy and skills are impressive.
Characteristics of corals
have you wondered what are corals?, the majority of corals are ordered in the class Anthozoa, despite the fact that there are some in another family category. They are hydrozoans that create calcareous skeletons, called burning corals in light of the fact that their bite is risky. They are family of coral reefs.
Numerous examples of marine corals and about 6,000 genera are known. Examples of hard corals can be discovered, which are those that show a rigid anatomy, others have an adaptable horny framework and others do not shape a support itself, but have spicules flooded in the dermal canvas, which ensures.
Many corals live in beneficial interaction with zooxanthellae (harmonious photosynthetic green growth) that give them most of their food. Some of these creatures live in huge provinces and others lonely. They have limbs around their mouths that allow them to get food that slips into the water.
As a stomach, they have a hole with a tissue called gastrodermis, which can be septate or with nematocysts (stinging cells, similar to the lion's mane jellyfish) and a pharynx that speaks with the stomach. Numerous species of corals structure reefs, they are those that currently have a beneficial interaction with zooxanthellae and are known as hermatypic corals.
The corals that do not frame the reefs are of the ahermatypal type. This is the group that will be used to learn about the different types of corals. Corals can mimic abiogenetically through different systems, but also perform sexual proliferation.
Hermatypic corals and examples
Hermatypic corals are the types of hard corals, they have a stony exoskeleton framed by calcium carbonate. This type of coral is dangerously harmed by what is classified as "coral fade." The shade of these corals originates from their advantageous relationship with zooxanthellae.
These microalgae, the fundamental source of vitality for corals, are being undermined by rising temperatures in the seas as a result of environmental exchange, overabundance in daylight and certain diseases. When the zooxanthellae die, the corals stain and die, so several coral reefs have disappeared.
To tell the truth, hermatypic corals are related to certain types of surface humidities that do not present some type of water contamination, which collect enough daylight to nurture the green growth of zooxanthellae that live in the tissues of their coral polyps. Some of them are:
- Acropora cervicornis
- Agaricia undata
- diploria clivosa
- Millepora squarrosa
Ahermatypic corals and examples
The main quality of these corals is that they do not have a calcareous framework, although they can establish a cooperative correspondence with zooxanthellae. In this way, they also do not shape coral reefs, they can be pioneers anyway.
The gorgonians whose skeleton is made up of a protein substance that they discharge are important in this meeting. In addition, within its fleshy tissue are the spicules, which function as help and security.
Corals of this class do not build reefs, since they do not create a supporting skeleton. They have eight limbs and are called octocorals, in turn they incorporate corals from the Alcyonacea application, as well as certain species in the application, for example, the gorgonians and the Sessiliflorae, they are also called delicate corals.
Unlike stony corals, they are adaptable, undulating in currents, and regularly punctured, with a silky appearance. Their skeletons are proteinaceous instead of calcareous. Meet some of them:
- Acanella sp.
- Irrigorgia sp.
The shape and spread of the spicules are the main attributes used in the distinguishing test of genera and types of octocorals. Delicate corals are marginally less abundant (20 species occur in the Caribbean, in contrast to 197 for hard corals) than stony corals.
Corals are oceanic wonders of great importance for aquatic ecosystems, each of them, regardless of the family they belong to, have a very useful leading role, many of them are part of the beautifying elements of the ocean world.
