Adults file snakes can grow up to 8.25 ft (2.5 m) in length. They have amazingly loose skin and are known to prey on large fish, such as eel-tailed catfish. Females are usually larger than males and they have been known to give birth to up to 17 young.
The indigenous peoples of Northern Australia often hunt these snakes as they are quite common. As the snakes are near immobilized without the support of water the hunters merely throw each newly caught snake on the bank and continue hunting until they have enough, they are then thrown on hot fire coals and buried for about 15 minutes.
