Lasiognathus saccostoma

Lasiognathus saccostoma has its dorsal fin supported by 7 or 7 soft rays while the anal fin contains 4 or 5 soft rays. The species in Lasiognathus are identified from one another by the morphology of their esca and in this species the bulb of the esca has no membrane-like crest on its front. The appendage on the tip has a cylindrical stalk with thin filaments emerging from the front base of the black hooks on the esca. The appendage on the rear of the esca is laterally flattened and rounded and has an irregularly rounded margin and wide base, emerging from under the escal pore. This species has a maximum published standard length of 7.7 cm (3.0 in).

Lasiognathus saccostoma has been recorded in warmer waters of the North Atlantic and northeast Pacific. Specimens have been collected in trawls from depths between 800 and 1,800 m (2,600 and 5,900 ft)>

Lasiognathus saccostoma is a member of the genus Lasiognathus, this name is a combination of lasios, meaning "bearded", and gnathus, which means "jaw". This may be a reference to the many long teeth in the upper jaw, goving the appearance of a beard. The specific name saccostoma, combines sakkos, which means "bag", "pouch" or "pocket", with stoma, meaning "mouth", a reference to the premaxillaries having a wide membrane which connects them to the head, this makes a membranous pouch, the "trap" of wolftrap, in which the fish holds its prey before swallowing it.
