The fourhorn poacher (Hypsagonus quadricornis, also known as the four-horned sea-poacher[2]) is a fish in the family Agonidae (poachers).[3] It was described by Achille Valenciennes in 1829, originally under the genus Aspidophorus (now Agonus).[4] It is a marine, temperate water-dwelling fish which is known from the northern Pacific Ocean, including the Sea of Okhotsk, the Sea of Japan, the Bering Sea, the Kuril Islands, and Washington (state) , United States . It is non-migratory, and dwells at a depth range of 0 to 452 metres (0 to 1,483 ft), most often at around 100 to 150 metres (330 to 490 ft). It inhabits sediments of sand and gravel. Males can reach a maximum total length of 12 centimetres (4.7 in), but more commonly reach a TL of 10 centimetres (3.9 in). The maximum recorded weight is 24 grams (0.053 lb), and the maximum recorded age is 7 years.[3]
The fourhorn poacher is preyed on by Hippoglossus stenolepis.[5] Its own diet consists of crustaceans including shrimp, crabs, isopods, amphipods, and ostracods, as well as bony fish, gastropods, and polychaetes.[6]
