Alligatorfish

The Alligatorfish (Aspidophoroides monopterygius, also known commonly as the Aleutian alligatorfish and the Atlantic alligatorfish[2]) is a fish in the family Agonidae (poachers).[3] It was described by Marcus Elieser Bloch in 1786.[4] 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, USA. It dwells at a depth range of 0–695 metres, most often around 60–150 m, and inhabits sand and mud bottoms mostly on the lower continental shelf all year. It prefers a temperature range of -1.07 to 2.52 °C. Males can reach a maximum total length of 22 centimetres, but more commonly reach a TL of 14.2 cm.[3]
