Beluga whales are naturally vocal animals. They are often called “canaries of the sea” thanks to their wide repertoire of sounds such as whistles, squeals, moos, chirps, and clicks. Some researchers believe they even found a beluga that tried to imitate human voices! Their smiling appearance and communicative nature make belugas very charismatic animals.
Though young belugas are gray or brown, adults are easily identified by their white coloring. This white color allows the beluga to blend into its habitat, the icy Arctic and subarctic waters. However it is not a perfect defense against the beluga’s predators, which include polar bears, killer whales, and humans.
