Description
Adults grown to 8.25 ft (2.5 m) in length. They have very 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 skin is used to make drums in New Guinea.

In Aboriginal language and culture
Arafura file snakes are often hunted by indigenous peoples of Northern Australia.

In the Kunwinjku language of West Arnhem Land, the snakes are known as kedjebe (or bekka in Eastern dialects), while in the Yolŋu language of East Arnhem Land they are called djaykuŋ, among other names.
