Crocodiles eat large prey by biting them into smaller pieces. They participate in what is known as supportive behavior, where the reptiles will cooperate in feeding on and breaking up prey to sizeable amounts.
Crocodiles mainly eat fish (Catfish) but will also ambush and fest on game meat such as antelope including Zebra and Buffalo. They can also be a danger to humans, as they will attack them and injure them or devour them.
On hot days, Crocodiles enjoy tanning in the sun on sandbars and river banks. Crocodiles loose excess heat by lying with their mouths open on hot summer days. They also enjoy swimming as it is a completely effortless task, they use their tails and webbed feet to allow careful maneuvering during mating and when preparing to ambush prey.
A Crocodiles nostrils and jugular close at the back of their mouth to help them breath under water. Crocodiles can live up to 60 to 100 years of age.
Crocodiles reach their sexual maturity when they are 12 to 15 years of age (2 to 3 metres, 70kg to 100kg). They take good care of their young, though males may eat them. Males struggle for the right to mate in a social hierarchy during mating season.
Mating takes place in water between July-August. The female will then select a suitable sunny sand bank above the flood waters mark, that has a good drainage and cover nearby. The female will then use this sand bank for the rest of her life unless it has been damaged.During November months the female will dig a hole 30 to 40cm deep, and lay anywhere between 16 to 80 hard, white eggs. The nest is then heavily protected against predators and other Crocodiles. Until the eggs hatch, the mother will refrain from eating and jealously guard the nest.The eggs will hatch between 84 and 90 days after they have been laid. When they hatch they can be heard by their loud, high pitched chirping sound that can be heard up to 20m away. The female will then carefully open up her mouth for the young ones to climb in and then take them down to the water where she will release them, staying close together in a group for 6 to 8 weeks.
