Taxonomy

Halieutopsis nasuta was first formally

Ogcocephaloidei within the order Lophiiformes, the anglerfishes in the 5th edition of Fishes of the World.[6]

Etymology

Halieutopsis nasuta has the genus name Halieutopsis which suffixes opsis, meaning "looking like" to halieut which is derived from halieutaea, Greek for an "angler" or "fisherman". This name is a reference to this genus' resemblance to the genus Halieutaea. The specific name nasuta means "large-nosed", an allusion to "the broadly expanded snout-bones project far beyond the deep semicircular cavity which lies beneath them”.[7]

The rostrum is obtuse bony shelf well overhanging mouth, consists of three simple, enlarged, upward- and forward-directed tubercles (Figure 21A). The

standard length of this species varies from 20.5 to 71.6 mm (0.81 to 2.82 in).[4]

Distribution and habitat

Halieutopsis nasuta is found in the tropical

Indo-West Pacific being recorded from Indonesia, Philippines, Solomon Islands, New Caledonia, Vanuatu and Australia. It occurs at depths between 297 and 1,141 m (974 and 3,743 ft), mainly between 300 and 600 m (980 and 1,970 ft).[8]
