Crocodiles

She then carries them  in  her mouth down to the water, where she will guard them for several more weeks or months until thy learn to hunt on their own.
Bats 
Bats become moms by hanging head up in a cave, giving birth. Catching the youngsters 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 to feed them. It continues for about three weeks, until the babies are grown up and able to fly on their own.
Koalas 
The animal mom gives birth after pregnancy 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 moths old.
