Dusky Shark


The Dusky Shark is often mistaken for the sandbar shark.

The Dusky Shark is a large shark with a long streamlined body. The upper side is brown to gray with the underside white.

They are very similar in appearance to the sandbar shark but can be distinguished by its smaller dorsal fin. The underside of the pectoral fins, anal fin and the lower caudal fin lobe darken towards the tips; this is more obvious in juveniles.

They have a defined interdorsal ridge (ridge of skin going down the back between the two dorsal fins).

The upper and lower teeth are nearly erect. The upper teeth are triangular with serrated edges. The lower teeth are narrower and more finely serrated.
