Fig. 5.
Halosaurus affinis, Günther 1877: 444 View in CoL . South of Japan, 34°N, 138°E, Challenger station 235, depth 565 fathoms. Syntypes: BMNH 1887.12.7.244-245 (2). McDowell 1973: 91 –101 (description, key); Maul 1976: 22 (description); Filatova 1985: 27 –29 (description), 33–34 (key); Sulak 1986a: 593 –598 (description, key); Mceachran & Fechhelm 1998: 210 –215 (description, key); Smith 2003 (key).
FIGURE. 4 Halosaurus johnsonianus View in CoL 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 GoogleMaps ; 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 View 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).
