Description

Also known as Black-pitted Sand Eel, Burrowing Snake Eel, Estuary Snake Eel, Worm Eel.

Found singly or in loose groups, usually buried, or with just their heads showing, in mud patches or sand, over estuaries, lagoons, and coastal reefs.
They feed nocturnally on crustaceans and small fish.
Length - 100cm
Depth - 1-25m
Widespread Indo-Pacific

Snake Eels resemble snakes or worms because they have virtually no fins. Their pointed snouts and tails allow them to burrow beneath the sand.
They can usually be found with just their head showing above the sand waiting for their prey, a few species prowl around the sands at night. Some mimic banded sea snakes and can be found in the open during the day. (edit) Ref: https://www.fishbase.se/summary/Pisodonophis-cancrivorus
