Atlantic spotted dolphin fact sheet



Spotted dolphins are characterised by their colouring and patterns of spots which vary with geographical location and age. The spots, which are absent at birth build up over time so that adults have a dense covering of spots. Two species of spotted dolphin exist: Pantropical (S. attenuata) and Atlantic (S. frontalis) which are encountered in the Azores and other subtropical and tropical areas off the Atlantic.

In the Azores, Atlantic spotted dolphins are seen between June and December, with the highest sighting rates being around August, when the water is warmest.  They are usually seen in large groups numbering up to several hundred or thousands. They travel in long, low leaps and often approach boats from a distance to ride in their bow.
