WHAT TO LOOK FOR

This shark has a smooth skin (block-shaped denticles wide spaced but not overlapping). It has a rather short and thick snout, and its first dorsal fin is quite short and high, with the second being almost as high with a spine base over its inner pelvic fin margins. There is a shallow notch in the postventral caudal fin margin of adults, and the lower lobe is moderately long.

COLOR

Dark grey or grey-brown on top, and lighter below with dusky fin webs and dark fin tips only in the juveniles.GULPER-SHARK-CENTROPHORUS GRANULOSUS
