Beluga whale

The beluga whale is a small, white Arctic cetacean that belongs to the dolphin family and is known for its remarkable vocal abilities, earning it the nickname "canary of the sea." These intelligent marine mammals live in cold Arctic and sub-Arctic waters around the North Pole, where they communicate with each other using clicks, whistles, and knocking sounds that scientists study to understand their behavior and social structures. Belugas are also notable for their flexible neck, rounded head shape, and lack of a dorsal fin, adaptations that help them navigate through sea ice and hunt for fish and squid in their icy ocean habitat.
