Alligatorfish maximum total length of 22 centimetres, but more commonly reach a TL of 14.2 cm. The Alligatorfish is preyed on by the Atlantic halibut ("Hippoglossus hippoglossus") and the Pacific halibut ("Hippoglossus stenolepis"). Its own diet consists primarily of benthic crustaceans and bottom fauna. Alligatorfish The Alligatorfish (Aspidophoroides monopterygius, also known commonly as the Aleutian alligatorfish and the Atlantic alligatorfish) is a fish in the family Agonidae (poachers). It was described by Marcus Elieser Bloch in 1786. It is a marine, temperate water-dwelling fish which is known from the northwestern Atlantic Ocean, including western Greenland; Labrador, Canada; and Cape Cod, Massachusetts,
Pelagic fish ocean floor consists of abyssal plains, but these flat, featureless regions are covered with sediment and largely devoid of benthic life (benthos). Deep sea benthic fishes are more likely to associate with canyons or rock outcroppings among the plains, where invertebrate communities are established. Undersea mountains (seamounts) can intercept deep sea currents, and cause productive upwellings which support benthic fish. Undersea mountain ranges can separate underwater regions into different ecosystems. Small pelagic fish are usually forage fish that are hunted by larger pelagic fish and other predators. Forage fish filter feed on plankton and are usually less than 10 centimetres
