Rissos Dolphin Description
  Risso's dolphins are quite easy to identify, especially when they get older. This is because they become scarred and battered due to being scratched by the teeth of other Risso's dolphins. They only have teeth in the front of their lower jaw and these are used when playing or fighting.
When born they are grey all over, and then become chocolate-brown and eventually pale grey with a pale underside. Their flippers and tail remain darker though, and the flukes are broad with pointed tips.
They have a very tall dorsal fin which can be up to 50cm in length, the tip of which may be curved or pointed.
Instead of a beak, it has a blunt head with bulging forehead that slopes steeply to the mouth which curves upwards.
