Question

Why are offspring of oviparous animals at a greater risk as compared to offspring of viviparous animals?

Prabhat Rajore · Accepted Answer

Oviparous animals lay eggs outside of their body. Thus, the eggs have to face the harsh environmental conditions like excessive heat or cold, predators, water scarcity etc. On the other hand, in viviparous animals, the development of the egg takes place inside the body of the female. The egg is well protected from the unfavourable conditions. Hence, the offspring of an egg-laying or oviparous animal is at greater risk as compared to the offspring of a viviparous animal, which gives birth to its young ones.  - Wired Faculty
