FIGURE. 4 Halosaurus johnsonianus from the northeastern Atlantic Ocean, MHNUSC 25013- 2, 404 mm total length.
Material examined. MHNUSC 25011- 1, 423 mm TL, 7th August 2011, Galicia Bank; 42º56.172'N— 11º55.816'W; 1,545 m depth; MHNUSC 25011- 2, 486 mm TL, 7th August 2011, Galicia Bank; 42º41.771'N— 11º33.647; 1,477 m depth; MHNUSC 25011- 3, 442 mm TL, 2th August 2011, Galicia Bank; 42º56.172'N—11º55.816; 1,545 m depth.
Description. Body shape eel-like, moderately compressed, elongated and attenuated to the caudal peduncle; top of snout and head scaleless, opercle scaleless; the preoral portion of the snout is long, contained 2–2.2 times in the snout length; first ray of dorsal fin very short and spine-like; pectoral fin short and fairly broad, falling well short of origin of ventral fin; dorsal fin origin slightly posterior to pelvic fin origin; palatine tooth patch joined at midline; pyloric caeca black and vent white. The main morphometric and meristic characteristics are presented in Table 6.
Habitat and distribution. Benthopelagic on the middle and lower slope (700–2,200 m), occurring primarily above the 4° C isotherm. Circumglobal at tropical and temperate latitudes. Eastern Atlantic, from Gulf of Biscay, Madeira to western Sahara, off South Africa; western Atlantic, from New England to Florida, Gulf of Mexico, off the Caribbean islands and South America; Indo-Pacific, in Zanzibar, Maldives, Taiwan, Japan, and eastern central Pacific (Froese & Sampang 2004; Yeh et al. 2006).
