A rare sighting of sperm whales in the Canadian Arctic is the latest sign of a quickly changing ecosystem, say scientists, as a growing number of species expand their range into warming Arctic waters.
Brandon Laforest, a marine biologist with the World Wildlife Fund, and guide Titus Allooloo were working on a project monitoring the effect of marine traffic on the regions narwhal population when they spotted the pair of large whales just outside Pond Inlet, a community at the northern tip of Baffin Island in September.
Video of the incident, released at the end of October, captures the second known sighting of sperm whales in the region. In 2014, hunters from Pond Inlet spotted them in the area.
At first, Allooloo and Laforest thought the dark shapes in the water were killer whales another species that has become a frequent visitor to the waters as temperatures creep up. But the distinct shape of the dorsal fin surprised Allooloo a veteran hunter.
Theyre not known by us, we dont know too much about them, Allooloo told the CBC.
