These jellies are typically found at a depth of 250-1,500 meters deep in the North Pacific Ocean.
This mesopelagic jelly ranges in color from deep red, purple, or black to pale purple.
The deep color of its belly may mask the animal's bioluminescence to hide it from potential predators.
Its "combs," rows of cilia on its body, have a sparkling iridescence.
Lampocteis need to be able to conceal their stomach in order to prevent their prey from lighting them up from the inside, effectively revealing its location.
