The blue shark is a mostly pelagic species and the most wide-ranging shark in the world, inhabiting all temperate and tropical oceans. In the North Atlantic, it migrates over long distances in a circular pattern from Africa to North America, and then Europe, arriving in Canada in the spring and departing in the fall.
A number of blue sharks seasonally enter the Gulf of St. Lawrence where they have been recorded¹ reaching the mouth of the estuary off the Gaspé Peninsula.
