Nile Crocodile

The Nile crocodile is one of the most powerful predators in Africa’s rivers and lakes. After heavy hunting for skins in the twentieth century, it has recovered in many areas under protection.

Interesting facts

  • It is Africa’s largest crocodilian.
  • It can hold its breath for up to about an hour when resting.
  • Mothers carry hatchlings gently to the water in their jaws.
  • Crocodiles swallow stones, which may help with digestion and buoyancy.
  • Nest temperature determines the sex of the young.
  • Groups sometimes cooperate to herd fish.

Behaviour

Crocodiles bask in the sun to warm up and ambush prey from the water. Dominant males defend stretches of river or lake shore.

Breeding and young

Females lay 25 to 80 eggs in a nest dug in sand and guard it for about three months.

Threats and conservation

Locally, habitat loss, pollution, conflict with people and illegal killing.
