Chaenophryne longiceps, commonly known as the can-opener smoothdream, longhead dreamer or smooth-head dreamer, is a species of anglerfish in the family Oneirodidae (dreamers).[3][4][5][6][7]

Description

Chaenophryne longiceps is known for its monstrous appearance: inky black in colour with sharp pointed teeth (28–40 in upper jaw, 34–57 in lower) and (in females) a pointed lure (esca) protruding from its forehead.[8] The maximum length of females is 28 cm (11 in); the males are about 2 cm (0.79 in) and attach themselves to the female with special denticles, but are not parasitic.[9][10] It has 6–8 dorsal soft rays and 5–6 anal soft rays. Its specific name, longiceps, means "long head."[11]

Habitat

Chaenophryne longiceps is bathypelagic, living at depths of 500–1,000 m (1,600–3,300 ft) in tropical to temperate parts of all the earth's oceans. In 2010 it was found off Greenland for the first time.[12]

Behaviour

Feeds on fish, cephalopods and crustaceans.[11]
