What are Oviparous animals?
Oviparous animals are those that lay eggs. The eggs are then fertilized by the male and develop into offspring outside of the mother’s body. Some common oviparous animals include fish, amphibians, reptiles, and birds.
What are Viviparous animals?
Viviparous animals are those that give birth to live young. The young develop inside the mother’s body and are born when they are fully formed. These animals include mammals, such as humans and other primates, as well as some reptiles and amphibians.
Why are offsprings of oviparous animals at a greater risk as compared to offsprings of viviparous animals?
Offsprings of oviparous animals are at a greater risk as they are born outside of the mother’s body.
They are therefore exposed to a variety of environmental hazards, such as predators and harsh weather conditions.
Offspring of viviparous animals, on the other hand, are born inside the mother’s body and are protected from these hazards.
They are at greater risk because
1. Extreme weather conditions
The weather conditions outside can be very extreme, and it can be difficult for an egg to survive in these conditions. Eggs can also get crushed or eaten by predators.
2. Lack of protection
Eggs are unprotected and are therefore more susceptible to getting hurt or killed.
3. Exposure to predators
Eggs are a food source for many predators, and so the eggs are at risk of being eaten.
