Deepstaria is a genus of jellyfish known for their thin, sheet-like bodies. The genus is named after the Deep Star 4000, which collected the holotype of the type species, D. enigmatica.[1] This species is commonly found at depths of 600 to 1750 meters deep.

Description

Characteristic features of this genus include: a large, thin umbrella, lack of tentacles, and long oral arms.[2] Due to lack of tentacles and large size, Deepstaria captures prey by encapsulating the prey with its whole body[3] and digesting through their gastro-vascular canal system,[4] allowing for proper distribution of nutrition, circulation of oxygen, and waste removal.

As of 2017, WoRMS recognizes two species within the genus:[5]
