背棘 (總數) : 0; 臀棘: 0. A slender, dwarf catshark with 2 equal-sized dorsal fins and a long tape-like caudal fin (Ref. 5578). Grey-brown in color (Ref. 5578).
一個細長又矮小的貓鯊有兩個大小相同的背鰭與一個長的帶狀尾鰭。 (參考文獻 5578) 灰褐色顏色.(參考文獻 5578)
Found on the upper continental slope and outer shelf (Ref. 244). Feeds on small bony fishes, crustaceans and cephalopods (Ref. 244). Ovoviviparous (Ref. 50449), with 2 young in a litter (Ref. 244). Geographic or bathymetric segregation of populations by sex probably occurs as most specimens taken off Natal were male (Ref. 244).
