Toronto-born behavioural ecologist Alexander Wilson has discovered an unlikely friendship in the North Atlantic.
A group of sperm whales have apparently adopted a bottlenose dolphin with a spine deformity, swimming alongside him and at times nuzzling and rubbing up against him, at least temporarily.
Wilson and partner Jens Krause of the Leibniz-Institute of Freshwater Ecology and Inland Fisheries in Berlin made the discovery in 2011 while observing sperm whales about 15 to 20 kilometres off the island of Pico in the Azores.
