Imvelaphi yazo zonke izinto eziphilayo emhlabeni yenzeka ku- imvelo yasemanzini. Kuwo wonke umlando wokuziphendukela kwemvelo, izilwane ezincelisayo bezilokhu ziguquka futhi zivumelana nezimo zobuso bomhlaba kuze kube, eminyakeni eyizigidi ezimbalwa edlule, ezinye zazo zibuyele ekucwiliseni olwandle nasemifuleni, zivumelane nempilo ngaphansi kwalezi zimo.

Kule ndatshana yePeritoAnimal, sizokhuluma ngayo izilwane ezincelisayo zasemanzini, eyaziwa kangcono njengezilwane ezincelisayo zasolwandle, njengoba kusezilwandle lapho inani elikhulu kakhulu lezinhlobo zalolu hlobo lihlala khona. Yazi izici zalezi zilwane nezinye izibonelo.

Izici zezilwane ezincelisayo zasemanzini

Impilo yezilwane ezincelisayo emanzini yehluke kakhulu kuleyo yezilwane ezincelisayo ezisemhlabeni. Ukuze baphile kule ndawo, bekufanele bathole izici ezikhethekile ngesikhathi sokuvela kwabo.

Amanzi aphakathi nendawo aminyene kunomoya futhi, ngaphezu kwalokho, anikeza ukumelana okukhulu, yingakho izilwane ezincelisayo zasemanzini zinomzimba i-hydrodynamic ngokweqile, okubavumela ukuba bahambe kalula. ukuthuthukiswa kwe- amaphiko Okufana nalokho kwezinhlanzi bekumele ushintsho olubalulekile lwe-morphological, olubavumele ukuthi bandise ijubane, baqondise ukubhukuda futhi baxhumane.

Amanzi ayindlela yokungena ebamba ukushisa okukhulu kakhulu kunomoya, ngakho izilwane ezincelisayo zasemanzini zinoqweqwe olujiyile lwamafutha ngaphansi kwe- isikhumba esiqinile futhi esiqinile, okubagcina bevikelekile kulokhu kulahleka kokushisa. Ngaphezu kwalokho, kusebenza njengesivikelo lapho behlala ezindaweni ezibandayo kakhulu emhlabeni. Ezinye izilwane ezincelisayo zasolwandle zinoboya ngoba zenza imisebenzi ethile ebalulekile ngaphandle kwamanzi, njengokukhiqiza kabusha.

Izilwane ezincelisayo zasolwandle, ngezikhathi ezithile zokuphila kwazo, ezihlala ekujuleni okukhulu, zenze ezinye izitho ukuthi zikwazi ukuhlala ebumnyameni, njenge i-sonar. Umuzwa wokubona kulezi zindawo zezinto eziphilayo awusizi ngalutho, njengoba ukukhanya kwelanga kungafinyeleli kulokhu kujula.

Njengazo zonke izilwane ezincelisayo, lezi zilwane zasemanzini zinezindlala zomjuluko, izindlala ezincelisayo, ezikhiqiza ubisi lwezingane zazo, futhi zikhuculise amathumbu emzimbeni.

Ukuphefumula kwezilwane ezincelisayo zasemanzini

izilwane ezincelisayo zasemanzini badinga umoya ukuze baphefumule. Ngakho-ke, baphefumula umoya omningi futhi bawugcine ngaphakathi kwamaphaphu isikhathi eside. Lapho bejula ngemuva kokuphefumula, bayakwazi ukuqondisa kabusha igazi liye ebuchosheni, enhliziyweni nasemisipha yamathambo. Imisipha yakho ine-protein ephezulu ebizwa ngokuthi myoglobin, ekwazi ukuqoqa umoya-mpilo omningi.

Ngale ndlela, izilwane zasemanzini ziyakwazi ukuhlala isikhathi eside ngaphandle kokuphefumula. Imidlwane Encane Nisanda Kuzalwa abanalo leli khono elithuthukisiwe, ngakho-ke bazodinga ukuphefumula kaningi kuneqembu lonke.

Izinhlobo zezilwane ezincelisayo zasemanzini

Izinhlobo eziningi zezilwane zasemanzini zihlala endaweni yasolwandle. Kunemiyalo emithathu yezilwane ezincelisayo zasemanzini: i-cetacea, i-carnivora ne-sirenia.

i-cetacean oda

Ngaphakathi kwe-cetaceans, izinhlobo ezimele kakhulu imikhomo, amahlengethwa, imikhomo yesidoda, imikhomo ebulalayo nama-porpoise. AmaCetacean aguquke enhlotsheni yezilwane ezidlayo zomhlaba ngaphezulu kweminyaka eyizigidi ezingama-50 edlule. I-oda le-Cetacea lihlukaniswe ngama-suborder amathathu (okukodwa kwanyamalala):

• i-archaeoceti: izilwane zasemhlabeni ezine-quadrupedal, okhokho bama-cetaceans amanje (asevele ephelile).
• Imfihlakalo: imikhomo yokugcina. Ziyizilwane ezidla inyama ezingenamazinyo ezithatha amanzi amaningi zihlunge ngasesifubeni, zicoshe izinhlanzi ezibhajwe kuyo ngezilimi zazo.
• odontoceti: Lokhu kufaka amahlengethwa, imikhomo ebulalayo, ama-porpoise noziphu. Iqembu elihluke kakhulu, yize isici salo esikhulu ukuba khona kwamazinyo. Kuleli qembu singathola ihlengethwa elibomvana (I-Inia geoffrensis), Izinhlobo zezilwane ezincelisayo zasemanzini ezihlanzekile.

ukuhleleka kokudla

Ku-oda lokudla, kufakiwe izimvu zamanzi, amabhubesi olwandle nama-walrus, yize ama-otter asolwandle namabhere asezindaweni ezibandayo nawo angafakwa. Leli qembu lezilwane lavela eminyakeni eyizigidi eziyi-15 edlule, futhi kukholakala ukuthi lihlobene kakhulu nama-mustelids namabhere (amabhere).

I-oda le-Siren

I-oda lokugcina, i-siren, lifaka phakathi ama-dugong nama-manatees. Lezi zilwane zavela kuma-tetiterios, izilwane ezicishe zifane nezindlovu ezavela eminyakeni eyizigidi ezingama-66 edlule. Ama-Dugong ahlala e-Australia nase-manatees e-Afrika naseMelika.
