Myrichthys colubrinus

Myrichthys colubrinus, the banded snake eel, ringed snake eel or harlequin snake eel, is a snake eel from the Indo-Pacific. It occasionally makes its way into the aquarium trade. It grows to a size of 97 cm in length.

The ringed snake eel resembles the venomous sea snake, Laticauda colubrina which is a form of Batesian mimicry. It also adjusts its behaviour to swim freely during the day, whereas other snake eels tend to stay hidden and roam at night.

In 2021, it was first recorded in Hawaii.
