A large, relatively slender grey shark; snout moderately long and broadly rounded; eyes large, round; nasal flaps rudimentary; lip furrows short; upper teeth broadly triangular, serrated, straight to slightly oblique; lower teeth with high narrow straight points; a low ridge between dorsal fins; origin of first dorsal fin above about rear edge of pectoral fins; first dorsal fin moderately large (height 9.1-12.1% or more of TL), with straight front edge, its apex pointed or narrowly rounded, moderately concave rear edge its origin over rear 1/3 of inner margin of pectoral fin; origin of second dorsal fin about over anal fin origin; pectorals large, with narrowly rounded to pointed tips and straight rear edge.
