Etymology: Cirrhoscyllium: cirrus, Latin for curl or tendril, referring to barbels on throat; skylion, Greek for dogfish or small shark. (See ETYFish); expolitum: Latin for varnished, referring to how the shark’s body, when dry, “glistens as though varnished, owing to the peculiar character of the dermal denticles”. (See ETYFish).

Max length : 34.0 cm TL macho/indeterminado; (Ref. 247)
Espinhos dorsais (total): 0; Raios dorsais (total): 0; Espinhos anais 0; Raios anais : 0. Genus: pair of barbels on throat; color pattern of dark saddles, no light or dark spots (Ref. 43278).
Species: Six or possibly ten diffuse saddle marks on dorsal surface, saddles above abdomen rounded and continuing above pelvic-fin bases, not C-shaped, head length three times first dorsal-fin base (Ref. 43278). Gill region without collar marking (Ref. 13572).
Found on the continental shelf, offshore on or near the bottom (Ref. 247). Food habits unknown (Ref. 13572). Oviparous (Ref. 43278, 50449). Interest to fisheries unknown (Ref. 13572). Probably taken as discarded by-catch of offshore trawl fisheries in the area (Ref. 43278).
