Demersal fish can be divided into two main types: strictly benthic fish which can rest on the sea floor, and benthopelagic fish which can float in the water column just above the sea floor. Benthopelagic fish have neutral buoyancy , so they can float at depth without much effort, while strictly benthic fish are denser, with negative buoyancy so ...
An example of a flabby fish is the cusk-eel Acanthonus armatus, [58] a predator with a huge head and a body that is 90% water. This fish has the largest ears and the smallest brain in relation to its body size of all known vertebrates. [59] Robust benthopelagic fish are muscular swimmers that actively cruise the bottom searching for prey.
The term benthos, coined by Haeckel in 1891, [3] comes from the Greek noun βένθος 'depth of the sea'. [1][4] Benthos is used in freshwater biology to refer to organisms at the bottom of freshwater bodies of water, such as lakes, rivers, and streams. [5] There is also a redundant synonym, Benton. [6]
Halibut. Atlantic halibut. Halibut is the common name for three species of flatfish in the family of right-eye flounders. In some regions, and less commonly, other species of large flatfish are also referred to as halibut. The word is derived from haly (holy) and butte (flat fish), for its popularity on Catholic holy days. [1]
The common dentex (Dentex dentex) is a species of marine ray-finned fish belonging to the family Sparidae, which includes the seabreams and porgies. This species is found in the northeastern Atlantic Ocean and the Mediterranean Sea. It is a highly valued food fish and is an important target species for fisheries and the population has shown ...

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 live on or near the sea floor, while pelagic fish live in the water column away the sea floor. Examples of such shallow water demersal fish, found in both tropical and temperate waters around the world, are triplefins, seahorses, wrasse and flounder. As demersal fish, all these fish spend most of their time on or near the sea floor.
