Yes -- an organism is benthic if it lives on the bottom of a sea or lake. Starfish, or sea stars, tend to reside at the bottom of bodies of salt or brackish water
A starfish is a sessile benthic organism. While they are capable of movement, they primarily inhabit the sea floor and are often found attached to substrates like rocks or coral. They are not pelagic, as they do not live in the open water column.
Starfish have been known to live as deep as 6000m
The orange starfish mainly eats organisms that live in benthic zones. This includes barnacles, worms, and different types of mollusks.
Starfish are benthic predators. Since they usually eat shellfish like mussels or scallops, they would be second order consumers.
Consumers in the benthic zone, called Zoobenthos, can range from starfish in the intertidal zone, to bottom-dwelling flatfish, to deep sea Rattails. The type of consumer is highly dependent on the specific areas in the benthic zone.
