Female American alligators and African crocodiles are exemplary moms compared with other representatives of their class. They protect a special nest with eggs. Such nests are made of rotting plants, and female alligators and crocodiles keep a certain temperature there that is required for their brood. A female is always near her nest and does not let anyone near it. Before hatching baby reptiles start making quacking sounds. This is the signal for the mother to unearth her nest and help her offspring out, after which she carefully carries her babies to the “nursery” — a small pond protected with plants.
