خارهاي باله پشتي (کل) : 0; خارهاي باله مخرجي: 0. A small slender shark with a long narrowly rounded or somewhat pointed snout, no interdorsal ridge, small pectoral fins, a small first dorsal fin with an extremely long rear tip and a small low second dorsal fin with a long rear tip (Ref. 244). Back grayish or grey-brown, belly white; posterior margin of pectorals and ventral caudal fin lobe with an inconspicuous white edge; posterioventral and dorsal margins of caudal fin with a narrow black edge (Ref. 9997).
Body shape (shape guide): fusiform / normal.
Found in inshore and offshore waters of continental and insular shelves (Ref. 9997). Feeds mainly on fishes, also cephalopods and crustaceans (Ref. 6871). Viviparous (Ref. 50449). Of limited interest to fisheries due to its small size (Ref. 9997). Utilized fresh and probably dried-salted for human consumption (Ref. 244).
