| The Nile crocodile, Crocodylus niloticus, is the largest predator in Africa, growing up to 6 meters (20 feet) in length and weighing up to a metric ton. It lurks around water holes and prowls rivers and canals in search of game, taking nearly any animal it can grasp, drown, and swallow, including humans. Found throughout subtropical and tropical Africa and Madagascar, adults are uniformly colored; juveniles are speckled. This crocodile was once numerous in the Nile and elsewhere, but its numbers have declined since World War II because of loss of habitat, hunting, and nesting-site disturbance by humans. |
