Description

Stomias boa has an elongated body and small head;[8] it is up to 32.2 cm (1.06 ft) in length, black underneath and iridescent silver on its flanks, with a barbel that has a pale stem, dark spot at base of bulb and three blackish filaments.[9][10] It has six rows of hexagonal areas above a lateral series of large photophores.[11] The dorsal and anal fins are opposite each other, just anterior to the caudal fin.[12]

Distribution and habitat

Stomias boa is mesopelagic and bathypelagic, living at depths of 200–2,173 m (656–7,129 ft) in seas worldwide, particularly off the Atlantic coast of North America, in the Mediterranean and in a band 20°–45° S.[13][14][15] S. boa ferox is concentrated in the North Atlantic.[16] S. boa colubrinus is most common off the Congo coast and the northwest coast of South America.[17][18]

Diet

Stomias boa eats midwater fishes and crustaceans; it rises to near the surface to feed at night.[10]

Reproduction

Stomias boa is oviparous; its larvae are 9–44 mm (0.35–1.73 in) in length.[19]
