DUSKY SHARK FACTS
The Dusky Shark is a large shark with a pointed snout, long curved pectoral fins and a ridge between the two dorsal fins. The first dorsal fin is tall and the second is low and broad. The upper teeth are triangular and serrated. The lower jaw teeth are more slender. The species is grey, blue-grey or grey-brown above with white underside. There is an indistinct stripe on the body from behind the gills to the tail. Juveniles have a dusky coloured lower tail lobe and underside of the pectoral fins. Fin markings are less prominent as the fish ages.
