edit_(20211931363).jpg)
The Arctic rockling's maximum length is 35 cm (14 in).[7] It has two dorsal fins and one anal fin, with the first ray in the first dorsal fin being elongated to form a whisker-like projection. It has 51–53 vertebrae (including urostyle).[8] The upper body is brown-red, its belly pink, there is a blue hue around its head, and the barbels and fin tips are red. The young are silvery in colour, hence the name.[2]
Habitat
editArctic rockling live in the northeastern Atlantic Ocean,[9] in very cold water, 0 °C (32 °F) or lower.[10] It is epibenthic, living over gravel, mud or sand at depths of 400–500 m (1,300–1,600 ft), sometimes as shallow as 150 m (490 ft).[2]
Behaviour
editArctic rockling feed on decapod, amphipod, and euphausiid crustaceans, and fish.[11]
