ama-cetaceans yiwo Izilwane zasolwandle edume kakhulu ngenxa yokuba khona kwabo ezindabeni zakudala nasezinganekwaneni. Yizilwane ezihlale zivusa isasasa elikhulu kubantu. Lezi zilwane, ngokuvamile, zingaziwa kakhulu ukuthi, kancane kancane, ziyanyamalala ngaphandle kwethu ngokusobala ukuthi azenzi lutho.
Kule ndatshana kaPeritoAnimal, sizokhuluma ngama-cetaceans - ukuthi ayini, izici zawo, lapho ahlala khona nezinye izifiso. Ngabe ufuna ukwazi okwengeziwe ngalezi zikhulumi zolwandle olujulile? Qhubeka ufunde!
yini ama-cetaceans
I-oda lama-cetaceans lakhiwe ngama-suborder amabili, i- izimanga, okwakhiwa yimikhomo enentshebe, kanye odontocetes, eyakhiwa ama-cetaceans anamazinyo, njengemikhomo yesidoda, amahlengethwa nama-orcas.
Ukuvela kwama-cetaceans kuholele ekufaneni phakathi kwalezi zingxenye ezimbili eziphilayo, okuwumphumela we- ukuhlangana kwemvelo. Izici zokwakheka ezijwayele ukuhlangana phakathi kwala maqembu womabili, njengokuma komzimba, ukuma kwekhala noma isiphetho ngenhla kwekhanda, ukungabikho kwezintambo zezwi nokuma okufanayo kwamaphaphu, kusikisela ukuthi lezi zinhlobo zavela kokhokho abehlukene ziye ezilwaneni ifana kakhulu.
Ngakho-ke, izilwane ezincelisayo ze-cetacean yizilwane zamaphaphu ezihlala olwandle nasolwandle lwethu, yize izinhlobo ezithile zihlala emifuleni.
Izici zama-cetaceans
AmaCetaceans abonakala nge-anatomy, morphology, physiology kanye nendawo abahlala kuyo. Izici eziyinhloko zama-cetaceans yilezi:
- Babonisa ifayela le- ububanzi bomzimba ububanzi ngokukhethekile okuthonya ukugcinwa kwabo komoya-mpilo namandla wokusebenzisa. Lokhu kuvimbela i-hypoxia noma ukungabi khona komoya-mpilo ezicutshini zakho.
- Ngesikhathi sokuntywila, inhliziyo yakho idlulisela igazi ebuchosheni bakho, amaphaphu nemisipha ukuvumela ukubhukuda nokusebenza okuqhubekayo komzimba.
- I-trachea ifushane kunezilwane ezincelisayo zasemhlabeni futhi ayixhumani nomphimbo. Ixhunywe ku-spiracle, lapho imunca futhi ikhiphe umoya.
- unayo amadamu amakhulu amafutha ukuvimbela i-hypothermia lapho udonsela ekujuleni okukhulu.
- ifomethi i-hydrodynamic yomzimba wakho ivumela isivinini esikhulu sokubhukuda futhi ivimbela ukulimala ekushintsheni kwengcindezi enkulu.
- awunawo ama-vocal chords. Esikhundleni salokho banesitho esibizwa ngokuthi yi-melon abasisebenzisa ukuxhumana noma ukuzingela. i-echolocation.
- Ngabe isikhumba esijiyile kakhulu ungqimba lwayo olungaphandle, i-epidermis, luvuselelwa njalo ngejubane elikhulu.
- Ekuzalweni, imidlwane inoboya, kepha lokhu kuyanyamalala ngemuva kwezinyanga ezimbalwa zokuphila.
- Inani lamaphiko lincike ezinhlotsheni, yize zonke zinamaphiko e-pectoral ne-caudal.
- Ezinye izinhlobo zinamazinyo, alinganayo futhi omi ngokulingana. Abanye banezintshebe abazisebenzisa ukuhlunga amanzi.
ahlala kuphi ama-cetacean
Indawo ehlala ama-cetaceans yiyona imvelo yasemanzini. Ngaphandle kwakhe, isikhumba sabo besizoma bese befa. Amanye ama-cetaceans ahlala emanzini azungeza insimbi, ngokwesibonelo umkhomo i-beluga (I-Delphinapterus leucas) noma umkhomo wenarwhal (Monodon monoceros), ngakho-ke zivumelaniswa namazinga okushisa aphansi. Abanye basatshalaliswa ezindaweni ezishisayo ngokwengeziwe, njenge-whale yomzingelo (Izingoma zeGlobicephala) kanye nomkhomo wenqwaba yomshoshaphansi (IGlobicephala macrorhynchus).
Ezinye zalezi zilwane zihlala emanzini ahlanzekile futhi zisengozini enkulu yezinhlobo ze-cetacean, ikakhulukazi ngenxa yokungcola kwemifula, ukwakhiwa kwamadamu nokuzingela okubandlululayo. Uhlu lwama-cetaceans ahlala emifuleni ngu:
- Ihlengethwa laseBolivia (Inia boliviensis)
- Ihlengethwa i-Araguaia (I-Inia araguaiaensis)
- Ihlengethwa elibomvana (I-Inia geoffrensis)
- I-Porpoise (I-Pontoporia blainvillei)
- I-Baiji (i-vexillifer lipos)
- I-Indo-dolphin (platanist omncane)
- Ihlengethwa leGanges (u-gangetic platanist)
Iningi lama-cetaceans yenza ukufuduka kwaminyaka yonke kusuka ezindaweni zabo zokudla kuya ezindaweni zabo zokuzalela. Lesi yisikhathi lapho lezi zilwane zingavikelekile kakhulu.

Izinhlobo zama-cetaceans
AmaCetacean ahlukaniswa amaqembu amabili amakhulu: wena izimanga kanye ne- okukhethwa ngamazinyo.
1. Izimfihlakalo
izimanga, evame ukubizwa ngemikhoma, mancane kakhulu futhi abonakala kakhulu ngokuba namapuleti ezintshebe esikhundleni samazinyo. Ziyizilwane ezinobukhulu obukhulu kakhulu ezihlala emanzini abandayo. Ezinye zezinhlobo zayo azikaze zibonwe ngesikhathi sokubukwa kwe-cetacean amashumi eminyaka. Izinhlobo ezivame kakhulu zama-mysticites yilezi:
- I-Pacific Right Whale (I-Eubalaena japonica)
- Umkhomo waseGreenland (UBalaena mysticetus)
- I-Fin Whale (I-Balaenoptera physalus)
- I-Blue Whale (I-Balaenoptera musculus)
- umkhomo we-humpbackMegaptera novaeangliae)
- Umkhomo ompunga (U-Eschrichtius robustus)
- Umkhomo WasePygmy (ICaperea marginata)

2. Odontocetes
Odontocetes kukhona ama-cetaceans anamazinyo angempela, ngenombolo enkulu noma encane. Ziningi kakhulu futhi zifaka izinhlobo eziningi ezinhle. Zonke ziyizilwane ezidla inyama. Izinhlobo ezaziwa kakhulu zama-odontocetes yilezi:
- I-Longfin Pilot Whale (Izingoma zeGlobicephala)
- Ihlengethwa laseNingizimu (ILagenorhynchus australis)
- I-Orca (i-orcinus orca)
- Ihlengethwa elimthende (stenella coeruleoalba)
- Ihlengethwa iBottlenose (I-Tursiops truncatus)
- Ihlengethwa lase-Atlantic elimhlophe (Lagenorhynchus acutus)
- I-Twilight Dolphin (ILagenorhynchus obscurus)
- I-Porpoise (Phocoena phocoena)
- I-Vaquita (Phocoena sinus)
- I-Porpoise-of-glasses (I-Dioptric Phocoena)
- Umkhomo Wesidoda (Umzimba we-macrocephalus)
- Isidoda sePygmy (kogia breviceps)
- Isidoda Esincane (UKogia sima)
- Umkhomo Onomlomo KaBlainville (I-Mesoplodon densirostris)
- Umkhomo Womlomo KaGervais (mesoplodon europaeus)
- Umkhomo Onombala Okumpunga (mesoplodon grayi)
Emfanekisweni singabona i-whale yomshayeli evamile:
