Mertensia ovum

Commonly known as the “Arctic Comb Jelly” or “Sea Nut” Mertensia ovum is a species of cydippid ctenophore that occurs in Arctic and polar seas. Like many other ctenophores M. ovum is weakly bioluminescent and can produce a striking rainbow effect by beating their eight rows of cilia. Mertensia ovum is a carnivore and will feed on copepods and other small crustaceans that are snagged by its two sticky tentacles.
