I-Southern Right Whale, ingabe iyathandeka?
I-southern right whale inelukuluku lokufuna ukwazi futhi iyadlala nxazonke zabantu. Kube nezimo lapho bebefuna ukuthwala izikebhe ezincane nama-kayak emhlane wabo. Kujwayelekile ukuthi basebenzisane ngendlela enobungani namahlengethwa nemikhomo yama-humpback.

- Isisindo: amathani angama-47.
- Ukusabalalisa: Amanzi angaphansi kwe-subtropical kanye ne-sub-Antarctic ye-hemisphere eseningizimu.
- Isimo Sokongiwa: ukukhathazeka okuncane.

- Ukubukeka: okumpunga okumnyama noma okumnyama, kwesinye isikhathi okunamabala amhlophe ngaphansi.
Idla kanjani?
Umkhomo oseningizimu, njengoba sesishilo kakade, ungowomndeni wama-baleen whale. Ukuze zidle, zigwinya amanzi agcwele emlonyeni bese zivala umlomo wazo ukuze ziwakhiphe ngamapuleti akhethekile, aziwa ngokuthi ama-barbs, akwazi ukuhlunga amanzi futhi agcine ukudla. Ukudla okuvaleleke ebaleen yilokho okudliwa kamuva.
Kodwa-ke, ama-southern right whales anomehluko kwamanye ama-whales futhi lokho ukuthi abhukuda phakathi nezikole ze-krill evule imilomo, futhi akwazi ukuhlunga ama-krill ngesikhathi ehamba phambili, ngaphandle kokugwinya amanzi agcwele emlonyeni. .
Ungabhukuda ngokushesha kangakanani?
Ngokocwaningo, i-whale efanele ihamba kancane, ngoba ngokwesilinganiso, ibhukuda ngesivinini esingamakhilomitha angu-5 ngehora.
Anjani amasiko okuqomisana?
Abesifazane bafinyelela ekuvuthweni ngokocansi lapho sebeneminyaka engu-9 ubudala. Zizala njalo ngeminyaka emi-3 noma emi-4 kuphela. Isikhathi sokuzala sazo sisukela phakathi noJulayi kuya ku-August.
Insikazi izungezwe abesilisa abanothando. Eyensikazi izozungeza emhlane wayo ukuze igcine isitho sayo sangasese siphezulu, singaphandle kwamanzi, futhi singafinyeleli kwabesilisa kuze kube yilapho sesizizwa ukuthi sesikulungele ukuzala. Ukuhlangana akufinyelelwa ngaso sonke isikhathi ngenxa yezimpawu ezikhethekile zepipi lendoda, elingamamitha angu-3 ubude futhi likwazi ukulawuleka.
Amaduna uma engalwi ayadudulana ukuze athole insikazi. Uma isilungile, insikazi inikeza ukufinyelela okuningi kwabesilisa. Abesilisa bazobe sebekhiqiza igaloni lesidoda, esiqine ngokwanele ukudlula isidoda sabesilisa abandulele. Isikhathi sokukhulelwa sithatha unyaka ogcwele futhi lapho izalwa, ithole linesisindo esingamakhilogremu angu-1.500.
I-Southern Right Whale ihlala isikhathi esingakanani?
Kunombono wokuthi i-southern right whale iphila ngokwesilinganiso seminyaka engu-50 endle, kodwa ukwaziswa okutholakalayo kuyindlala futhi kunezibonelo zezinhlobo ezifanayo eziphila iminyaka efinyelela kweyikhulu.
Ngokwalokho okuye kwaphawulwa, kunemikhomo engaba ngu-10.000 XNUMX ebizwa ngokuthi i-southern right whale emhlabeni.
Ingabe i-Southern Right Whale inezilwane ezidla ezinye zemvelo?
Okwaziwayo ukuthi i-southern right whale ihlaselwa ama-cook gull asePatagonia. Ama-Gulls abangela inqwaba yamanxeba kuwo, ashiye izimbobo ezinkulu esikhumbeni semikhomo. Futhi, ngenxa yalokhu kulimala, imikhomo ichitha ingxenye enkulu yesikhathi sayo ibalekela ama-seagull, okusho ukuthi ichitha isikhathi esincane isondla amathole. Amankonyane awo asengozini yokuthola imikhomo ebulalayo noshaka abakhulu abamhlophe.
Amaqiniso angu-10 abalulekile mayelana ne-southern right whale
Imikhomo ibaluleke kakhulu olwandle. Kungashiwo ukuthi bangonjiniyela bezinto eziphilayo, ngoba babambisana ngezindlela eziningi ukuze bagcine ukuphila olwandle kunempilo, ngokusabalalisa kabusha imisoco olwandle ezindaweni ezihlukahlukene.
Umkhomo oseningizimu wenza umsebenzi ofanayo. Kodwa namuhla ikhaya labo emanzini omhlaba wonke aseNingizimu ye-Atlantic lisongelwa ukudoba kwezimboni. Kulesi sigaba sokuthunyelwe sizokutshela amaqiniso ayishumi ngomkhomo we-southern ozokuthakazelisa.
1.- Igama layo i-Eubalaena australis: Iwuhlobo lwe-cetacean yomndeni wakwaBalaenidae, indawo yawo yokuhlala itholakala eningizimu nenkabazwe, phakathi kuka-20 ° no-60 ° latitude eNingizimu Pacific, eNingizimu ye-Atlantic kanye nolwandle lwase-Indian. eningizimu.
2.- Ingomunye wemikhomo emikhulu kakhulu: Inobukhulu obuphakathi kwamamitha ayi-13 no-15 ubude uma kwenzeka kwabesilisa futhi cishe amamitha ayi-16 kwabesifazane. Isisindo sazo singamathani angama-40 futhi ekuzalweni avele abe nobude obungamamitha ama-3 kuya ku-5, ukusuka ekhaleni kuya emsileni.
3.- Zinezibazi esikhumbeni zazo ezaziwa kakhulu ngoba zisebenza njengeminwe, ngazo zonke lezi zilwane zikwazi ukubonakala umkhomo ngamunye ukuphila kwawo konke. Lawa ma-calluses izindawo eziphakeme zesikhumba, eziwugqinsi olungaphezu kwamasentimitha angu-5, ezivela ezingxenyeni ezihlukene zamakhanda azo.
4.- Izilwane ezincelisayo ezolile, ezithanda ukwazi futhi eziphuza ukubhukuda. Ukuze bakhulume bayagxuma bashaye amanzi ngamaphiko abo.
5.- Kucatshangwa ukuthi bangaphila phakathi kweminyaka engama-50 neyi-100 ubudala.
6.- Abanawo amazinyo, kodwa ama-baleen amade, okungamashidi e-keratin alenga emhlathini ongenhla womkhomo. Lezi zintshebe yizo ezizivumela ukuthi zidle ngokusefa, njengoba sike sachaza ngaphambili.
7.- Ukudla kwabo okuyinhloko i-krill nezinhlanzi ezincane.
8.- Ingxenye yesithathu yayo yonke imikhomo elungile emhlabeni isebenzisa amatheku avikelekile eNhlonhlo yaseValdés, e-Argentina, njengendawo yokuhlala yokukhwelana kanye nokuzala abantwana bayo phakathi kwezinyanga zikaMeyi noDisemba.
