Esinye sezigaba ezivame kakhulu sehlukanisa izilwane zasemhlabeni nezisemanzini, kuya ngemvelo ezihlala kuyo. Umehluko, empeleni, uvame ukuhlotshaniswa nendlela yokuphefumula, ngoba kuvamile ukuthi izilwane ezisemhlabeni zifake umoya-mpilo emoyeni, kuyilapho izilwane zasemanzini zinezikhukhula zokukhipha umoya-mpilo oncibilikisiwe emanzini.
IZILWANE EZIFANAYO
I- izilwane zasemanzini Yilabo abathembele emanzini ukuze baphile, iningi labo elikwazi ukuphefumula ngalo. Kukhona, nokho, ukuthi yize bephila emanzini, kumele beze phezulu bezothatha umoya-mpilo.
Ngokuvamile, ukwakheka komzimba wezilwane zasemanzini kukhethekile futhi kuhlotshaniswa nalesi sidingo sokuhlala kuleyo ndawo, kusukela abanye banamaphiko, abanye ama-basal disc noma amagobolondo: Lesi sigaba sezilwane bekufanele sivumelane nemvelo yokuphila yolwandle, amagagasi kanye nemisinga ehlukene yamanzi ekhiqizwayo. Izikali negazi eliphaphathekile nakho kuyizindlela zokubonakaliswa kwalolu hlobo lokuphila, ngoba bekufanele zivumelane namazinga okushisa ahlukene wamanzi.
Mhlawumbe uhlobo lwesilwane olujwayelekile kakhulu endaweni yasemanzini yilawa izinhlanzi, abadingi ukuphuma emanzini nganoma yiziphi izidingo zabo (kunalokho, ukuphuma emanzini yikhona okubabulalayo). Ubuningi bezinhlanzi emhlabeni bazenza iqembu ngokwazo, okungezika iqembu lama-vertebrate ngama-gill okuphefumula ngaphansi kwamanzi. Kodwa-ke, izilwane eziningi zasemanzini ziwela kwezinye izigaba, njenge izilwane ezincelisayo zasemanzini noma ama-echinoderms asemanzini.

IZILWANE ZOMHLABA
Ukuphila nokuhamba phansi noma emoyeni kuyisici esiyinhloko se- izilwane zomhlaba. Lesi sici yiso esenza zonke izilwane okungenzeka kube nokungabaza ngazo zibhalwe esigabeni sezisemhlabeni: leli qembu lifaka izilwane ezihlala emhlabeni kepha ezichitha isikhathi esiningi emanzini, noma izilwane ezihlala emhlabathini izinambuzane noma izinkalankala ezinesigaba sasemanzini emjikelezweni wempilo.
Ngokwesayensi yemvelaphi yezinhlobo zezilwane, izilwane zomhlaba zazingezona ezokuqala ukuvela, kepha zazivela ezilwaneni zasemanzini.
Kwakunalokho-ke, kwaba noguquko kusuka ekungeneni kokuhlala endaweni yasemanzini kuya endaweni yasemhlabeni (ubufakazi bemivubukulo bubonisa ukuthi ukungena kokuqala emhlabeni okwenziwe izidalwa zasolwandle kwakungaba yiminyaka eyi-530 yezigidi edlule). Kwisibalo esikhulu sezilwane, ithuba lokuhlala endaweni yasemhlabeni latholwa phakathi nenkathi phalaphala noma iMesozoic, nokuncane okuncane ngesikhathi se- cenozoic.
Ngaphakathi kwesigaba sasemhlabeni, ukuhlukaniswa kungenziwa ngohlobo lokudla (phakathi abadla inyama, imifino, omnivores nama-frugivores), noma ukuhlukaniswa ngezigaba kwesilwane (phakathi kwezilwane ezincelisayo, izinyoni, ama-amphibians, ama-mollusks nama-echinoderms).
