Oviparous

Because the newborn fish are large compared to the fry of oviparous fish, they are easier to feed than the fry of egg-laying species, such as characins and cichlids.

In most oviparous shark species, an egg case with the consistency of leather protects the developing embryo(s).

Oviparity Some species are oviparous like most other fish, laying their eggs in the water.

Oviparous animals producing eggs with thin tertiary membranes or no membranes at all, on the other hand, use external fertilisation methods.

The families of Cyprinodontiformes can be divided into three groups: viviparous and ovoviviparous (all species give live birth ), and oviparous (all species egg-laying).

The whale shark is now classified as ovoviviparous rather than oviparous, because extrauterine eggs are now thought to have been aborted.

This probably represents the velvet worm's original mode of reproduction, i.e., both oviparous and viviparous species developed from ovoviviparous species.
