Back to Mini-games  Threats to the giants

1. Harbour porpoise

It’s the smallest whale found in the St. Lawrence. Often, harbour porpoises are confused with dolphins but they’re a completely different species. Since the 1990s, thousands of accidental catches have led us to fear for its survival. Less threatened today, the harbour porpoise’s status is still cause for concern.

2. Beluga

Newborn beluga calves are brownish grey. When they are one year old, the juveniles are bluish grey and when they reach adulthood, they finally turn white. Native to the Arctic, the small St. Lawrence beluga population numbers about 900 individuals. The beluga is very fragile, and its survival is in danger.

3. Minke whale

Considered small for a whale, this 7 to 10 m-long “giant” is a very agile hunter. In the past, the minke whale was not often hunted due to its small size. Today, Norway and Iceland hunt it commercially. Japan is involved in “scientific” whaling.

4. Tic tac toe, the humpback whale

Known since 1999, this humpback whale is easy to recognize due to the telltale “X” on its right tail fluke. This female humpback whale is the only one sighted with a calf off the coast of Tadoussac.

5. Fin whale

The name of this fin whale is a reminder of an unfortunate encounter with a ship’s propeller. Collisions with ships are one of the main causes of death among whales. In the St. Lawrence, more and more initiatives have been launched to avoid them.
