Question

echidna being an oviparous animal,is considered a mammal.why?

Answer 1

The echidna is one of only five living species of Monotremes, an order of mammals that lay eggs rather than giving birth to live young, like all other mammals do. Modern monotremes are toothless, have leathery or bird-like beaks, and like birds and reptiles, they have only a single opening through which they lay eggs and eliminate waste.

Like other mammals, monotremes are warm-blooded. They have hair on their bodies and produce milk to feed their young.

In echidnas, the female lays eggs into a pouch of skin on her stomach, where she carries them until they hatch. Although they have mammary glands, monotremes do not have nipples like other mammals. Instead, milk is released through pores in the skin and the young suckle from these milk patches until they are mature enough to fend for themselves.
