The Nile crocodile reigns supreme in Africa. This crocodile is one of the largest lving reptiles. Crocodiles, alligators, gavials, and Cayman look much alike, and are all called crocodilians. They all have tough hides, long snouts, and sharp teeth to grasp their prey. Nile crocodiles have an average life span of 45 years in the wild and may lve up to 80 years in captivity.
Sexual maturity relates to size.
The female can lay about 25 to 100 eggs, which she covers with sand, then guards until they hatch 3 months later. Female crocodiles nest in November and December on sandy shorelines, dry steam beds, or riverbanks. These Nile crocodiles can be found throughout tropical and southern Africa and Madagascar rivers, freshwater marshes, estuaries, and mangrove swamps. When young crocodiles are hatching, either parent may help them out of the egg, by rolling it between their tongue and palate. This cracks the shell allowing for an easier escape.
