The St. Lawrence of the Whales

The Atlantic Ocean: approximately 4,830 km wide and 4,000 m deep. An immense playground for whales. However, every spring, thousands of them turn their backs on this habitat to enter the St. Lawrence, some of them travelling up the Estuary as far as the mouth of the Saguenay, thousands of kilometres from their breeding grounds. Why? The St. Lawrence is teeming with fish and plankton, and feeding is the main activity of the summer. This habitat is also in the heart of the summer range of the St. Lawrence beluga, which spends its entire life there.
