Detailed explanation-1: -Despite their prehistoric look, crocodiles are among the more biologically complex reptiles. Unlike other reptiles, a crocodile has a cerebral cortex and a four-chambered heart. Crocodilians also have the functional equivalent of a diaphragm by incorporating muscles used for aquatic locomotion into respiration.
Detailed explanation-2: -Female crocodiles have long been known as attentive parents, carrying their newly hatched offspring in their mouths from sandy nests on land to the water and even manipulating intact leathery eggs in their mouths to liberate slow-hatching babies.
Detailed explanation-3: -Crocodiles bury their eggs in riverside nests. For up to three months, the mother waits nearby, protecting her eggs from predators or any other danger. As soon as the baby crocodiles are ready to hatch, they start to chirp. The mother digs down to the nest and carries her babies to the water in her mouth.
