How do Crocodiles build their nests?
Crocodiles are egg-laying reptiles, and the first thing a female must do after she has mated is build a nest.
Most species scoop up mud and plants in their jaws and build a mound of rotting vegetation. Then the female makes a hollow in the center and lays anything from 20 to 70 eggs in it. Afterwards, she covers them up and leaves them, but she does not stray far away.
The eggs are kept warm by the heat of the sun and the fermenting vegetable matter. When the young are ready to hatch, they make loud, hiccough-like noises which bring the mother to her nest.
She scratches the top of the nest away and the young break out of their shells. The young use their strong egg tooth, which has developed on the tip of the snout, to chip through the shell. This special tooth is lost soon after hatching.
