Etymology: Lasiognathus: Greek, 'lasios' = hairy or wooly + Greek, 'gnathos' = jaw (with reference to the huge number of long teeth of the upper jaw) ( Ref. 86949).; amphirhamphus: Name from the Greek 'amphi' (both sides or double) and 'rhamphus' (hook), alluding to the two bony, hooklike denticles of the esca of this species..
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 1200 - 1305 m (Ref. 56229). Deep-water
Eastern Central Atlantic: Madeira Abyssal Plain.

Morphology | Morphometrics
soft rays: 5. Escal bulb without membranous anterior crest; the distal escal appendage an elongate, cylindrical stalk, with an expanded distal end and an elongate, compressed prolongation emerging anteriorly from bases of escal hooks, without lateral serration. But bearing tiny filaments at distal tip. Prolongation of distal escal appendage extremely short, 2.9% SL (vs. 5.2-20.8% SL). There are 2 lightly pigmented, bony, hooklike denticles embedded in esca. Posterior escal appendage laterally compressed, with a rounded posterior margin and pointed distal tip (Ref. 56229).
