Striped Dolphin Stenella coeruleoalba 

Striped dolphins are relatively small, streamlined and colourful. As the name suggests, the most recognisable features are the ‘stripes’. A dark grey stripe runs from the beak, above the eye, across the flank and then down to the underside of the body. A second stripe runs below the eye to the pectoral flipper. Image: Alexandre Roux (Flickr).
