This is a Beluga Whale (Delphinaptera leucas) calf with its mother. I see this as a touching moment reflecting the closeness between mother & calves among all whales.

To learn more about Beluga Whales in the St. Lawrence River, as well some information and insight into these amazing animals, I suggest reading: Beluga: A Farewell to Whales, by Dr. Pierre Beland.
