Size

Length: 2.5 to 5.5m; Weight: up to 1000 kg or more.

Habitat

Distribution

The Nile crocodile is the most common crocodilian found in Africa today.

Diet

Up to 70% of the adult diet is fish. Other prey items may include zebras, hippos, porcupines, pangolins, and migrating wildebeest.

Socialisation

Crocodiles are gregarious animals. Groups of crocodiles are known as "floats" when in the water, and on lands, groups are referred to as "basks". The group sizes depend primarily on availability of or abundance of food sources and may range from as few as two crocs to as many as 200 individuals in a group.

Reproduction

Sevual maturity relates to size. Males are mature at about 10 feet at approximately 10 years of age, wheras females at about 6.5 feet at approximately 10 years of age.

Incubation: females nest in November and December on sandy shorelines, dry stream beds, or riverbanks.

A female may lay 25 to 100 eggs, which she covers with sand, then guards until they hatch 3 months later. 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.

Life Expectancy

45 years in the wild, up to 80 years in captivity.

Predators

  • Nile crocodiles have no natural predators.
  • Outside water, crocodiles can meet competition from other dominant savannah predators, notably lions and leopards
