An unusual sighting of Risso's dolphins near Benjamin Island.

Two Risso’s dolphins washed ashore in Hrútafjörður in Northwest Iceland last week. Risso dolphins are a warm-water species found a bit to the east of Ireland and Northwest Scotland. But the largest number is found further south, in warmer seas.

A closeup view of a bottlenose dolphin shows signs of skin lesions associated with a deadly skin disease known as ulcerative dermatitis. The increasing frequency and severity of storm systems drastically decrease the salinity of coastal waters, causing fatal skin disease in dolphins worldwide.

Bottlenose dolphins on Scotland’s east coast are expanding their range and swimming further south, according to one of the world’s longest-running studies of the species.

The eyewitness, who first heard the animal splashing by the southeastern coast, said she couldn't believe her eyes.

Unusually active marine mammals seen near Unalaska may actually be Pacific white-sided dolphins.
