This deep-sea mud star, Dytaster insignis, is a species which occurs in the true abyss, 2,515-3,530 meters (8,250-11,580 feet)! Although this individual was observed on the surface, it and other related “mud star” species are often seen buried just below the surface of muddy or sandy bottoms. This and related species are commonly collected with their disks engorged with mud. They have swallowed the sediment in order to devour potential snails and clams as well as other small organisms.
