Common dolphin fact sheet

Common dolphins are strikingly marked with a distinct yellow and grey hourglass pattern along their sides. They are divided into two distinct species: long-beaked (D. capensis) and short-beaked (D. delphis).  

In the Azores, the short-beaked variety are seen year round. They are often more brightly coloured than the long-beaked variety, and they have a greater range throughout most temperate and tropical waters of the Pacific and Atlantic. Common dolphins typically travel in large social groups which sometimes include up to thousands of individuals.  They often break the surface at high speed and frequently bowride in front of boats.
