A group of baby crocodiles in called a cr che. Eggs and hatchlings are subject to predation by baboons, marabou storks and monitors by day, and by hone badgers, white tailed mongooses and other predators at night. They have a lifespan of 70 to 100 years. Their diet varies with age. The juveniles eat spiders, frogs, insects, snakes, lizards and other small vertebrates.
Fish make up a substantial part of the diets of older offspring and adults.
Larger, mature Nile crocodiles capture zebras, antelope, wart hogs, large domestic animals and human beings. Crocodiles grab the large mammals at the edge of the water, drag them underwater and drown them.
