A large group of common bottlenose dolphins (Tursiops truncatus) have been spotted in Canadian Pacific waters -- the first confirmed occurrence of the species in this area. The sighting is reported in a study published in the open access journal Marine Biodiversity Records.

On 29 July 2017, researchers from Halpin Wildlife Research, in collaboration with the Department of Fisheries and Oceans, Canada and the Department of Environment and Climate Change, Canada, observed a group of approximately 200 common bottlenose dolphins and roughly 70 false killer whales (Pseudorca crassidens). The sighting occurred off the west coast of northern Vancouver Island, British Columbia, Canada and may be the northern most recording for this species in the eastern North Pacific.

Luke Halpin, lead author of the paper, said: 'It is surprising to find a warm-water dolphin in British Columbian waters, and especially to find such a large number of common bottlenose dolphins within the group."

This is the conclusion of a study which has, for the first time, counted these mammals in summer and spring, which are crucial seasons for them.
