What the speaker says is the common misconception about crocodile mothers?
Today we begin a new topic in our course on the survival of young animals, and I’d like to start with an explanation of a common misconception. Many people have heard that crocodiles eat their babies. Well, in fact they don’t. What happens is that the mother crocodiles take all their newly hatched youngsters into their mouths in order to carry them to the safety of the water. The reason is that the female crocodile must leave the water in order to hatch her eggs. She goes to the beach and digs a hole approximately 10 inches deep. She then lays her eggs in the hole and covers them with soil, using her body and tail to pat down the earth. While she guards her nest during the day and night for about 12 weeks, the sun heats the soil and hardens it. Then, when the baby crocodiles hatch, they find it almost impossible to get out, and they begin yelping and croaking. The mother hears them and rips open the nest. Then she takes the young into a pouch of skin in her lower jaw, and carries them to the safety of the ocean water before she releases them.
