CBC:

An unusual visitor has been hanging out in the St. Lawrence River for the past three years: A narwhal, more than 1,000 kilometres south of its usual range.

But the lone narwhal is not alone — it appears he has been adopted by a band of belugas.

The narwhal — thought to be a juvenile male because of its half-metre-long tusk — was filmed in July playing among a pod of young belugas, thought to be mostly or all males.

In Canada, even our whales are friendly.
