Angler's lantern

The angler's lantern was a species of jellyfish found in the Sea of Moving Ice.

Description
These creatures were named for their highly bioluminescent organs, which made it easier to spot them during the night.

Ecology
Angler's lanterns were believed to be active at any hour of the day, but it was hard to confirm this, owing to the difficulty of spotting them during daylight hours.
