Risso's Dolphins have strange body proportions with a relatively large head and and 'upper' body that tapers substantially to a small, thin tail. Adults can reach weights of 1,000 lbs and the coloration changes from dark at birth to iterations of whitish-grey as adults that are marked by linear scars that come from social interactions.
