La ukukhiqizwa kwezinhlanzi Kuyinqubo ethakazelisayo ehlukahluka kuye ngezinhlobo zezilwane nendawo ezihlala kuyo. Kunamasu ahlukahlukene okuzala avumela lezi zilwane ukuba ziqhubekisele phambili izinhlobo zazo futhi ziqinisekise ukuthi inzalo yazo iyasinda. Kulesi sihloko sizoxoxa ngokuningiliziwe izinhlobo ezahlukene zokukhiqiza izinhlanzi, sibeka ukugcizelela okukhethekile izinhlanzi ezinamaqanda, ngaphezu kokukhuluma ngezilwane ze-viviparous kanye ne-ovoviviparous.
Izinhlobo zokuzalana kwezinhlanzi
Izinhlanzi zingazalana ngezindlela ezihlukahlukene kuye ngokuthi imibungu ikhula kanjani. Izigaba eziyinhloko yilezi:
