Abstract

The specimen was relatively robust with unique body, head was blunt without distinct beak. Compared to other dolphins the forehead was bulging with relatively more squarish profile than the rounded melon. A prominent vertical crease on the front side of the melon was noticed. The dorsal fin was relatively tall and slender with a pointed tip. The flippers were relatively long. The upper jaw had only one pair of worn teeth and the lower jaw had six pairs of worn-down teeth. With the available morphometric information including the absence of beak, blunt-head and its overall size, with its bulk ahead of the dorsal fin, it was identified as Grampus griseus.
