Status in World Register of Marine Species:
Accepted name: Harriotta raleighana Goode and Bean, 1895 (updated 2009-06-25)

Diagnosis: snout tip long and pointed, bent upward; profile of forehead convex; eyes moderate, above mouth, their diameter 1.6-2.0 times in distance between eye and dorsal spine; tooth-plates with ridges and knobs. First dorsal fin with strong spine, straight, hind edges serrated; space between first and second dorsal fins shorter than base of first; pectoral fins wide and long, their tips reaching beyond pelvic fin origin; upper part of caudal fin normal, lower part longer and about twice as deep, the fin ending in a long filament (up to a third TL if undamaged). Colour: uniformly brown, fins edged darker, pelvic fins blackish. Size: to 120 cm TL (or 70 cm to origin of upper part of caudal fin).

Habitat: benthopelagic on continental slopes at about 360-2,000 m; locally not rare. Food: no data. Reproduction: oviparous; smallest known specimens about 10 cm to start of upper part of caudal fin.

Distribution: Rockall Trough northward to Iceland; probably also occurring further south in Clofnam area. Elsewhere, the Canaries; western North Atlantic between Nova Scotia and Chesapeake Bay, also southern Brazil; Pacific off New Zealand, Japan and California.

Note: a second species, H. haeckeli Karrer, 1972, is known from a few North Atlantic specimens from 1,800 to 2,600 m; one was caught at 27° 27' N, 14° 52' W, thus the species may also be found in deeper parts of the Clofnam area.
