Ravi’s younger brother of class III stated that bats are like birds as they are able to fly.
How will you contradict him and make him understand that bats are mammals and not birds?
Flight is not only the criteria for classifying bat as birds. The features that bat has which prove that it is a mammal and not a bird are:
i. External ears
ii. Body covered with hairs and mammary glands.
iii. They have skin instead of feathers and mouth.
iv. They have teeth instead of the beak.
v. They do not lay eggs but give birth to young ones.
How useful is the study of the nature of body cavity and coelom in the classification of animals?
Could the number of eggs or young ones produced by an oviparous and viviparous mother be equal? Why?
If you are given a specimen, what are the steps that you would follow to classify it?
What are the modifications that are observed in birds that help them fly?
