Actinopterygii (ray-finned fishes) > Lophiiformes
(Anglerfishes) > Ogcocephalidae
Etymology: Halieutopsis: Greek, halieutis = fisher + Greek, opsis = apperance (Ref. 45335); bathyoreos: From a species of a deep mountain (Ref. 40825).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathydemersal; depth range 960 - 1500 m (Ref. 40825). Deep-water
Pacific Ocean: off Japan, Hawaiian Islands, and New Zealand.

Morphology | Morphometrics
soft rays: 4;
Vertebrae: 19. This species is distinguished from its congeners in having the following characters: subtriangular disc in outline; illicial trough and esca fully visible in ventral view; tubercles on dorsal surface with 6-8 facets (Ref. 92977); a shelflike rostrum extending anteriorly well beyond the mouth; a dorsal, relatively wide, leaf-shaped dorsal escal lobe slightly bisected ventrally; an illicial cavity completely square in outline and completely visible from the ventral view; tubercles absent on ventral surface of disk (Ref. 40825, 55719). Additional characters due to its redescription (Ref. 55719) are: rostrum width 21-29% of head length; tubercles on the dorsal surface of the disk about half the diameter of those on the lateral margin; and, 13-15 large lateral-line scales on the tail (Ref. 55719).
Holotype taken from a depth of 1,500 m (Ref. 33390). Minimum depth from Ref. 58018.
