The story behind it
Saltwater crocodiles have the strongest bite of any living animal, generating a force strong enough to crush bone easily, though the muscles that open the jaw are surprisingly weak, so a person can hold a crocodile's mouth shut with just their hands. Despite their name, they can survive in both salt and fresh water thanks to special glands on their tongue that remove excess salt from their body. These crocodiles are ambush hunters, lying motionless for hours before exploding into a burst of speed to grab prey at the water's edge, then dragging it underwater in a spinning move called a death roll. They can also travel long distances by riding ocean currents, occasionally turning up far out at sea. Once heavily hunted for their skin, saltwater crocodiles have recovered well under protection and are now least concern.
Find it on the globe
Saltwater crocodile is there as a tiny animated figure that breathes and looks around. From far away the planet is only a blue ball; detail arrives as you zoom in, and this one appears once you are close enough. Open it on the globe.
It sits at its real coordinates, not near them — the same numbers listed in the facts above. Switch off the layer for this kind of place and it disappears again; the buttons for that are down the right-hand edge.
Questions children ask
What is the strongest bite in the animal kingdom?
The saltwater crocodile has the strongest measured bite force of any living animal, powerful enough to crush bone. Oddly, the muscles used to open its jaw are quite weak compared to the muscles that snap it shut.
Can saltwater crocodiles swim in the ocean?
Yes, saltwater crocodiles can travel long distances through open ocean by riding currents, and special glands help them get rid of extra salt. This is how they have reached remote islands far from any river.
What is a death roll?
A death roll is a spinning manoeuvre crocodiles use after grabbing prey, twisting their whole body rapidly to disorient the animal, tear off pieces, or drag it underwater, since crocodiles cannot chew their food.
