A bottom feeder is an aquatic animal that feeds on or near the bottom of a body of water. [1] Biologists often use the terms benthos —particularly for invertebrates such as shellfish, crabs, crayfish, sea anemones, starfish, snails, bristleworms and sea cucumbers —and benthivore or benthivorous, for fish and invertebrates that feed on ...
Demersal fish, also known as groundfish, live and feed on or near the bottom of seas or lakes (the demersal zone). [ 1 ] They occupy the sea floors and lake beds, which usually consist of mud, sand, gravel or rocks. [ 1 ] In coastal waters, they are found on or near the continental shelf, and in deep waters, they are found on or near the ...

Brown bullheads are omnivorous benthic bottom feeders. Their diet consists of algae, leeches, worms, mollusks, crustaceans, insects, crayfish, other smaller fish species and fish eggs. [8] [19] Brown bullheads are typically nocturnal feeders, but have been reported
Filter feeders, such as sponges and bivalves, dominate hard, sandy bottoms. Deposit feeders, such as polychaetes, populate softer bottoms. Fish, such as dragonets, as well as sea stars, snails, cephalopods, and crustaceans are important predators and scavengers.

Quillbacks benefit the ecosystem they reside in because they are bottom feeders. Bottom feeders help keep their natural environment clean by feeding on the material at the bottom of the habitat. The quillback has an economic benefit to Mexico. The IGFA world record for the species stands at 8lb 1oz taken from Lake Manitoba in Canada in 2016. [18]
