Crocodile Snake Eel

Found singly, with just the head showing, during the day buried in broken coral, rubble, and sandy substrates, of shallow lagoons and coral reefs, ready to ambush their prey.
Rarely out in the open during the day.

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.
