(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 (38 in) 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.
