The Nile crocodile is one of the largest and most widespread crocodilians in Africa. Adults commonly reach 3.5 to 5 meters, with some exceptional males exceeding 5.5 meters. They inhabit rivers, lakes, and wetlands across much of sub-Saharan Africa.
They can be distinguished from alligators by their narrower, more V-shaped snout and the visibility of the fourth tooth on the lower jaw when the mouth is closed.
Hunting and diet
Nile crocodiles are ambush predators. They wait motionless at the water’s edge or partially submerged, then strike with speed. Prey ranges from fish and birds to antelope, zebras, and occasionally larger animals that come to drink. They are also known to take livestock and, rarely, people.
Large adults can exert tremendous bite force and will drown or tear apart prey too large to swallow whole. They often cache food underwater or under banks.
Reproduction and behavior
Females dig nests in sandy banks and lay 25 to 80 eggs. They guard the nest and later carry hatchlings to the water in their mouths. Temperature during incubation influences the sex of the offspring.
Outside the breeding season, crocodiles may bask in groups, but they are generally territorial, especially large males.
Conservation
The species is listed as Least Concern overall, though some local populations have declined due to hunting and habitat loss. They remain common in many protected rivers and lakes.
Respect for their power and preferred habitats is the best way to avoid conflict in areas where people and crocodiles share the water.
