Whistle, click, chirp, or sing your way through the week with the beluga whale (Delphinapterus leucas)! Known as the “canary of the sea,” this cetacean uses a wide array of sounds to communicate with fellow belugas and navigate the open ocean. This social animal lives in a pod, roaming the Arctic waters and foraging for salmon, cod, and crab. Because the beluga whale is so reliant on sound, one of the greatest threats it faces is underwater noise pollution, from commercial ship traffic to dredging.
