Stomias boa ferox is a subspecies of deep-sea fish in the family Stomiidae. [3] [4] [5]
Stomias boa ferox has an elongated body and small head; [6] it is up to 30 cm (0.98 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. [7] [8] It has six rows of hexagonal areas above a lateral series of large photophores. [9] The dorsal and anal fins are opposite each other, just anterior to the caudal fin. [10] It can be distinguished from the S. boa boa subspecies by its larger number of photophores. [11]
The subspecies name ferox means "wild, ferocious." It is sometimes called dragon-boa, dragonfish or boa dragonfish, [12] [13] but those names are equally applied to Stomias boa as a species, or the S. boa boa subspecies. In Icelandic it is marsnákur ("sea snake") and in Norwegian storkjeft ("big jaw"). [14] [15]
Stomias boa ferox is mesopelagic and bathypelagic, living at depths of 20–800 m (66–2,625 ft), concentrated in the north Atlantic. [16] [17]
Stomias boa ferox eats midwater fishes and crustaceans; it rises to near the surface to feed at night. [8] It positions itself horizontally in the water column with pelvic and pectoral fins spread wide and barbel pointing forward. [18]
