The female crocodile, once fertilized, lays eggs, which can go up to sixty per nest. During the entire incubation period of 80 days, she will watch over her born to be without interruption and very often without feeding. Once they are ready to come out of their shell, their mother delicately carries them in her mouth to the river. Did you know, unlike humans, the sex of a crocodile will be determined by the temperature it makes in the nest: at 31.5 ? it will be an male, if it does more or less hot it will be a female.
