背棘 (总数) : 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).
一个细长又矮小的猫鲨有两个大小相同的背鳍与一个长的带状尾鳍。 (参考文献 5578) 灰褐色颜色.(参考文献 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).
