Risso's Dolphins in the Azores

On my five dolphin watching trips from the island of San Miguel in the Azores at least two produced sightings of Risso's Dolphins, including a scattered party of about ten animals. Unlike Common Dolphins, the Risso's are shy and don't usually come close to the boat. They are quite big and lack a prominent beak. Interestingly, they are born black but as they age they become progressively paler turning almost white; they also acquire extensive scarring which is thought to be a result of encounters with other Risso's Dolphins.
