Dusky dolphin  (Lagenorhynchus obscurus)

The dusky dolphin is a medium-sized dolphin, which is easily recognised by the evenly sloping head from the blowhole to the tip of the snout, which lacks a beak. As the common name suggests, the back and tail of this species are a dusky bluish-black, with a dark band running diagonally across the flanks to the tail. The underside is white and the tips of the snout and lower jaw are dark. A grey area runs from the eye to the flipper, and two cream stripes extend from the tail to the blunt dorsal fin (2).
