Are mammals born alive or in a egg?

Answer 1

Alive

**********************

Most mammals are born fully formed [infant version of the adults] and do not hatch from eggs.
Most mammals are born alive.

There are two egg-laying mammals. The platypus and the echidna are both egg-laying mammals, or monotremes.They are still classified as mammals because they feed their young on mothers' milk - a characteristic unique to mammals alone.

There are just three known species of egg-laying mammals, or monotremes. They are the platypus and short-beaked echidna (Tachyglossus aculeatus) of Australia, and the long-beaked echidna (Zaglosssus bruijni) of Papua New Guinea. The echidna is sometimes called the spiny anteater, and there are several sub-species of the long-beaked echidna: the Western long-beaked echidna, Sir David's long-beaked echidna and the Eastern long-beaked echidna.

Answer 2

Most mammals are born alive. There are just three exceptions to this, and they are the platypus, the short beaked echidna and the long beaked echidna. These three animals are egg-laying mammals, and classed as "monotremes".

Answer 3

Birds are alive in the egg, where they are maturing and growing. They are just as much alive when they hatch as when they are in the egg.

Answer 4

Most mammals have live birth. These are called placental mammals. Monotremes (the echidna and platypus) are more primitive mammals and lay eggs.
