See Hundreds of Beluga Whales Gathering in the Arctic

Up to 800 beluga whales gathered together north of Baffin Island in Lancaster Sound, Canada. They migrate here to give birth and molt dead skin. They're called the "canaries of the sea" for the many high-pitched vocalizations they use to communicate. Lancaster Sound is Canada's largest marine protected area, and contains other wildlife such as polar bears and seals.
