Question

Animal moms are great moms. You might be surprised at some of these moms.

Octopuses

The octopus mother lays about 50,000 eggs. For about 300 days, she stays with the eggs, cleans them and protects them. She does not leave to feed. However, this animal mom dies as soon as the eggs are hatched.

Crocodiles

A crocodile mother puts a lot of time and effort into raising her babies. She starts by building a nest(巢), which she guards for over two months! When the eggs are ready to hatch, the young crocs call out to their mother, who digs them out and helps them hatch. She then carries them in her mouth down to the water, where she will guard them for several weeks or months until they learn to hunt on their own.

Bats

Bats become moms by hanging head up in a cave, giving birth. Catching the youngster before it can fall to the ground below, she puts it in a pouch. Bat moms may carry babies with them when feeding for the first few days. As the little bats get bigger and heavier, moms help them hang on the wall of their caves and return often to feed them. It continues for about three weeks, until the babies are grown up and able to fly on their own.

Koalas

This animal mom gives birth after a pregnancy(怀孕期) of only 35 days. The hairless baby climbs into its mother's pouch and lives there for another five months. When the little koala is between five and eight months old, it leaves the pouch for short periods of time but returns for safety. Once it is too big to return to the pouch, it will climb onto its mother's back and ride there until it is about 12 months old.
