Saltwater crocodile

1. The saltwater crocodile Crocodylus porosus is an enormous creature and the world's largest living reptile. The average male is 5m in length, but reports exist of individuals measuring more than 8m.

2. It has a huge range that extends from northern Australia to eastern India and South-east Asia.

3. The temperature of the nest in which eggs are laid determines the sex of the offspring. Lower incubation temperatures produce mostly females; higher temperatures mostly males.

4. Salties have long lifespans, with many living to more than 65 years.

5. They are known to be fantastic swimmers and can travel long distances by sea, sometimes as much as 900km.

6. Salties have a valve at the bottom of the mouth that seals it off from their throat, enabling them to open their mouths underwater.

7. They typically feed on fish, mammals and birds, preferring to hunt at night.

8. Salties are known for the 'death roll' - a hunting behaviour reserved for larger prey. After drowning its victim, the crocodile rapidly rolls it in the water in order to remove its limbs.
