Vancouver Aquarium researchers are investigating after the body of a rare dolphin washed up on the shores of Haida Gwaii over the weekend.
The researchers were notified of the find by two local residents on Saturday evening.
An 11-foot-long Risso’s dolphin, also known as grampus, after its scientific name Grampus griseus, was found on a beach in Tlell, on the east coast of Graham Island.
A full necropsy was conducted on Monday. Although the researchers couldn’t see an immediate cause of death, they collected samples for genetic testing, as well as blubber and organ samples, and fluid samples for algal toxin testing.
The skeleton was also collected and, after cleaning, will be re-articulated and displayed locally.
The Risso’s dolphin is a large dolphin that is found in tropical and temperate waters around the world.
It can grow up to four metres long, has a light grey, stocky body covered with scratches and scars, with dark grey flippers, flukes and a tall, curved dorsal fin. Its head is rounded, with no noticeable beak.
It’s not a common species to see in B.C., but sightings have been reported before, usually on the coast of Haida Gwaii or on the west coast of Vancouver Island. It is not considered to be at risk in Canada.
Marine sightings can be reported with the WhaleReport app, by calling 1-800-I-SAW-ONE, or by emailing sightings@vanaqua.org.
