Common Name Leafscale gulper shark 
Redlist Status VU IUCN Redlist: Vulnerable(VU) A2bd+3bd+4bd 2003-04-30   
Characteristic The snout is moderately long, broadly parabolic, and the preoral snout is almost equal to the mouth width but shorter than the distance from mouth to pectoral origins; the upper anterolateral teeth are with erect to semioblique cusps. The first dorsal fin is relatively low and long; the second dorsal is moderately large, as high or higher than the first with a base of about 2/3 in length of the first dorsal base, and the spine origin is about over the rear tips or inner margins of pelvic fins; the distance from the first dorsal insertion to the origin of second dorsal spine is about as long as the tip of the snout to pectoral midbases in adults. The free rear tips of pectoral fins form broad angles, not expanded into the elongated lobes and not reaching to the level of first dorsal spine, the inner margins are shorter than the distance from second dorsal spine to caudal origin. The caudal fin is with a shallowly concave postventral margin in adults. The lateral trunk denticles overlap one another, with slender pedicles elevating flat, leaflike crowns, a strong main cusp and 3 or more pairs of lateral cusps on their posterior edges in adults (lateral cusps increase from a pair in young species with denticle replacement upon growth).
habitats Found on or near the bottom of continental slopes; also found pelagically in the upper 1,250 m of water 4,000 m deep. Presumably feeds on fish and cephalopods. Ovoviviparous. 
Distribution Irregularly distributed in the Eastern Atlantic, Western Indian Ocean, and Western Pacific (Taiwan, Japan, Philippines, southeastern Australia, and New Zealand). 
Utility Utilized dried salted for human consumption and as fish meal.
