Give the important features of class Mammalia.

Answer:
The important features of class Mammalia are:

  • They are warm-blooded animals.
  • Their heart is four-chambered.
  • They have mammary glands which produce milk with which they nourish their young ones.
  • They give birth to young ones, with the exception of platypus and echidna. Kangaroos give birth to very poorly developed young ones.
