Like humans, animal reproduction always starts with two reproductive cells. For mammals, everything happens in the female's belly: the fecundation and gestation. They're viviparous! Sometimes, fecundation takes place in the female's belly but then, the fetus grows up in an egg that the female lays. They're oviparous! And, for fish, how does it work? The female produces eggs but doesn't lay them, everything happens inside her body! They're ovoviparous!
