Rough Toothed Dolphin Description
  Rough-toothed dolphins get their name from the vertical ridges or wrinkles found on their teeth. However, as these are impossible to see, other features must be relied on when identifying them. They can be mistaken for bottlenoses but unlike other dolphins, rough-toothed dolphins do not have prominent beaks with a crease between their beak and forehead. Their long narrow beak blends smoothly into the forehead and some people have described them as looking like reptiles. Their skin is dark grey or blue-grey, sometimes with a hint of purple. The area around their mouths is often white or pinkish white especially on the underside where the whiteness covers the throat too. They have large eyes which are surrounded by a dark patch of skin. Rough-toothed dolphins have quite slim bodies, especially behind the dorsal fin which has a wide base and curves backwards. Their flippers are large and set quite far back on their body. The flukes have pointed tips and a notch in the middle. Rough-toothed dolphins often have spots or blotches on their lower body and they are often scarred too. They have between 38 and 52 teeth in the upper jaw and between 38 and 56 in the lower jaw. Different populations may look slightly different to each other, especially the animals living in the Atlantic and the Indo-Pacific population.
