WHAT ARE VIVIPAROUS AND OVIPAROUS ANIMALS?
We have learnt that some animals give birth to young ones while some animals lay eggs which later develop into young ones. The animals which give birth to young ones are called viviparous animals. Those animals which lay eggs are called oviparous animals. The following activity will help you understand better and differentiate between viviparous and oviparous animals.
Activity 9.2:
* Try to observe eggs of the following organisms – frog, lizard, butterfly or moth, hen and crow or any other bird.
* Were you able to observe eggs of all of them?
* Make drawings of the eggs that you have observed.
The eggs of a few animals are easy to observe because their mothers lay them outside their bodies. These are examples of oviparous animals. But you would not be able to collect the eggs of a dog, cow or cat. This is because they do not lay eggs. The mother gives birth to the young ones. These are examples of viviparous animals.
Can you now give some more examples of viviparous and oviparous animals?
