cetaceans ndi Nyama zam'madzi otchuka kwambiri chifukwa chakupezeka kwawo m'nthano zakale ndi nthano zakale. Ndiwo nyama zomwe nthawi zonse zadzutsa chidwi chachikulu kuchokera kwa anthu. Nyama izi, zambiri, sizikudziwika zomwe, pang'ono ndi pang'ono, zimasowa popanda ife kuchita chilichonse.

Munkhaniyi ndi PeritoZinyama, tikambirana za cetaceans - zomwe ali, mikhalidwe yawo, komwe amakhala komanso chidwi china. Kodi mukufuna kudziwa zambiri zamomwe amapangira nyanja yakuya? Pitilizani kuwerenga!

Kodi cetaceans ndi chiyani

Dongosolo la cetaceans limapangidwa ndi magawo awiri, a zinsinsi, zopangidwa ndi anamgumi amphepete, ndi odontocetes, wopangidwa ndi ma cetaceans okhala ndi mano, monga anamgumi aumuna, ma dolphin ndi orcas.

Kusintha kwa ma cetacean kwabweretsa kufanana pakati pamagulu awiriwa, chifukwa cha kusinthika kosinthika. Zomangamanga zomwe zimafanana pakati pamagulu awiriwa, monga mawonekedwe a thupi, malo amphuno kapena chotumphukira pamwamba pamutu, kusowa kwa zingwe zamawu komanso mawonekedwe ofanana am'mapapo, akuwonetsa kuti mitundu iyi idasintha kuchokera ku makolo awo kupita kuzinyama ofanana kwambiri wina ndi mnzake.

Chifukwa chake, nyama zakutchire ndizinyama zam'mapapo zomwe zimakhala m'nyanja ndi m'nyanja zathu, ngakhale mitundu ina imakhala mumitsinje.

Makhalidwe a cetaceans

Cetaceans amadziwika ndi matupi awo, kafukufuku wamakhalidwe, thupi ndi malo okhala. Makhalidwe apamwamba a cetaceans ndi awa:

• Amawonetsa fayilo ya misa ya thupi mwapadera kwambiri zomwe zimakhudza kusungira kwawo mpweya ndi magwiritsidwe ake. Izi zimalepheretsa hypoxia kapena kusowa kwa mpweya m'matumba anu.
• Pakutsika, mtima wanu umasunthira magazi kubongo lanu, mapapo ndi minofu yolola kusambira ndikugwira ntchito mosalekeza kwa thupi.
• Trachea ndi lalifupi kuposa nyama zakutchire ndipo sililumikizana ndi kholingo. Ndi yolumikizidwa ndi spiracle, komwe amayamwa ndi kutulutsa mpweya.
• khalani malo osungira mafuta ambiri kupewa hypothermia mukamayenda pansi kwambiri.
• mtundu hydrodynamic Thupi lanu limalola kusambira kwakukulu ndipo limalepheretsa kuwonongeka pakusintha kwakukulu.
• alibe zomveka zamawu. M'malo mwake, ali ndi chiwalo chotchedwa vwende chomwe amagwiritsa ntchito polumikizana kapena kusaka. echolocation.
• Khalani nawo khungu lakuda kwambiri yemwe gawo lakunja kwake, khungu, limasinthidwa nthawi zonse mwachangu kwambiri.
• Pakubadwa, ana agalu amakhala ndi ubweya, koma izi zimasowa patapita miyezi ingapo.
• Chiwerengero cha zipsepse chimadalira mitunduyo, ngakhale kuti yonse ili ndi zipsepse za pectoral ndi caudal.
• Mitundu ina ili ndi mano, onse ofanana kukula ndi mawonekedwe. Ena ali ndi ndevu zomwe amagwiritsira ntchito kusefa madzi.

kumene cetaceans amakhala

Malo okhala acetaceans ndi chilengedwe m'madzi. Popanda iye, khungu lawo limauma ndipo amafa. Ma cetacean ena amakhala m'madzi ozungulira, mwachitsanzo namgumi wa beluga (Delphinapterus leucas) kapena nsomba ya narwhal (Monodon monoceros), kotero amatha kusintha kutentha. Ena amagawidwa m'malo otentha kwambiri, monga Whale Whale woyenda nthawi yayitali (Nyimbo zapadziko lonse lapansi) ndi chinsomba chofupikitsa ()Globicephala macrorhynchus).

Zina mwa nyamazi zimakhala m'madzi oyera ndipo ndizoopsa kwambiri za mitundu ya cetacean, makamaka chifukwa cha kuwonongeka kwa mitsinje, kumanga madamu ndi kusaka kwatsankho. Mndandanda wa zikuluzikulu zomwe zimakhala mumitsinje ndi:

• Chidole cha Bolivia (Inia boliviensis)
• Araguaia dolphin (Inia araguaiaensis)
• Dolphin ya pinki (Inia geoffrensis)
• Mbalame (Pontoporia blainvillei)
• Baiji (PA)vexillifer lipos)
• Indo-dolphin (wotsutsa zazing'ono)
• Ganges dolphin (wotsutsa)

Ambiri a cetaceans kupanga kusamuka pachaka kuchokera kumalo awo odyetserako ziweto mpaka kumalo awo oberekera. Ino ndi nthawi yomwe nyamazi sizitetezedwa kwambiri.

Mitundu ya cetaceans

Ma Cetacean amadziwika kuti ndi magulu awiri akulu: inu zinsinsi ndi zotsukira mano.

1. Zinsinsi zanga

amatsenga, amatchedwa anamgumi, ndi ocheperako ndipo amadziwika kwambiri pokhala ndi mbale zandevu m'malo mwa mano. Ndi nyama zazikulu kwambiri zomwe nthawi zambiri zimakhala m'madzi ozizira. Mitundu ina yamtundu wake sinakhalepo pakuwona nyama zakutchire kwazaka zambiri. Mitundu yofala kwambiri yamatsenga ndi awa:

• Nsomba Yam'madzi yaku Pacific (Eubalaena japonica)
• Whale wa Greenland (Chinsinsi cha Balaena)
• Whale Wakale (Balaenoptera physalus)
• Whale Blue (Balaenoptera musculus)
• Nangumi (Megaptera novaeangliae)
• Whale wofiirira (Eschrichtius robustus)
• Pygmy Whale Wanyama (Caperea marginata)

M'chithunzichi titha kuwona Whale Wakale:

2. Odontocetes

Odontocetes ali cetaceans okhala ndi mano enieni, ochulukirapo kapena ochepa. Ndizochuluka kwambiri ndipo zimaphatikizapo mitundu yosiyanasiyana yazinthu zosiyanasiyana. Onsewo ndi nyama zodya nyama. Mitundu yodziwika bwino ya odontocetes ndi:

• Longfin Woyendetsa Whale (Nyimbo zapadziko lonse lapansi)
• Kumwera kwa Dolphin (Lagenorhynchus australis)
• Orca (Orcinus orca)
• Dolphin yamizere (stenella coeruleoalba)
• Dolphin ya botolo (Tursiops truncatus)
• Atlantic dolphin yoyera (Lagenorhynchus acutus)
• Masewera a Twilight (Lagenorhynchus obscurus)
• Porpoise (Phocoena phocoena)
• Vaquita (Phocoena sinus)
• Porpoise-of-magalasi (Dioptric Phocoena)
• Whale Whale (Thupi macrocephalus)
• Umuna wa Pygmy (kogia breviceps)
• Umuna Wamadzi (Kogia sima)
• Nangumi Wankhosa wa Blainville (Mesoplodon densirostris)
• Whale Wosungidwa ndi Gervais (mesoplodon europaeus)
• Whale Wofiirira (mesoplodon grayi)

Ngati mukufuna kuwerenga zina zambiri zofanana ndi Cetaceans - Tanthauzo, Mitundu ndi Makhalidwe, tikukulimbikitsani kuti mulowe mu gawo lathu la Curiosities la nyama.
