Good to know

Six things about the crocodile

Bite

The strongest bite

The Nile crocodile has one of the strongest bites ever measured in a living animal.

Waiting

A patient hunter

It can lie still for hours with only its eyes and nostrils above the water, waiting for an animal to come and drink.

Teeth

Thousands of teeth

Crocodiles replace their teeth all through life, and may get through several thousand.

Mother

A careful mother

The female guards her nest for three months, then carries the hatchlings to the water in her mouth.

Eggs

Warm eggs, male babies

Whether an egg becomes male or female depends on how warm the nest is.

Age

Older than the dinosaurs' end

Crocodiles have changed very little in tens of millions of years, and their relatives lived alongside the dinosaurs.

How to spot one

Look on sandbanks on a cool morning, where they bask with their mouths open. In the water, look for two bumps: the eyes and the nostrils.

How to help

Crocodiles keep rivers healthy by eating sick and dead fish. They need clean, undisturbed rivers and sandbanks to nest in.
