About the Crocodile
Nile crocodiles are Africa's largest reptiles and one of the world's most powerful apex predators, with a bite force of 22,000 Newtons — the strongest recorded for any living animal. Ancient survivors whose lineage dates back 200 million years, they have changed remarkably little since the age of dinosaurs.
Crocodile Fun Facts for Kids
- 1Crocodiles have the strongest bite force of any living animal — 22,000 Newtons, vs a human's 890 N.
- 2They carry their hatchlings gently in their mouths to the water — one of the most surprising displays of parental care in the reptile world.
- 3Crocodiles cannot chew — they swallow prey whole or use the 'death roll' to tear off chunks.
- 4Their eyes, ears, and nostrils are all on top of their heads so they can sense prey while almost completely submerged.

Common Questions
Crocodile Questions & Answers
How strong is a crocodile's bite?+
The Nile crocodile has a measured bite force of approximately 22,000 Newtons (about 5,000 lbs of force) — the strongest bite of any living animal. By comparison, a great white shark bites at around 18,000 N and a human at roughly 890 N.
How long do Nile crocodiles live?+
Nile crocodiles live 70–100 years in the wild, making them one of the longest-lived reptiles. The oldest verified captive crocodile lived to approximately 115 years.
What do crocodiles eat?+
Nile crocodiles are apex predators that eat fish, birds, turtles, and large mammals including wildebeest, zebra, and buffalo. They are opportunistic ambush hunters, lying motionless for hours before exploding forward to seize prey at the water's edge.
Are crocodiles and alligators the same animal?+
No. Crocodiles and alligators are related but distinct animals. The easiest way to tell them apart: when a crocodile's mouth is closed, the large fourth tooth on the lower jaw is still visible; in alligators it is hidden. Crocodiles also tend to be lighter in colour and have a more V-shaped snout.
How fast can crocodiles move?+
In short bursts on land, Nile crocodiles can reach 12–14 km/h (8 mph). In water they are much faster swimmers, reaching up to 32 km/h (20 mph) using powerful tail strokes. Their speed on land is often underestimated.
