📖 1. Overview
The Beluga is a white whale living in seas near the Arctic, called the 'canary of the sea' for the many sounds it makes.
🦴 2. Anatomy & Morphology
Adults are pure white all over while calves are pale gray. It has no dorsal fin, a small rounded head, and a more flexible neck than other whales. Its thick blubber layer forms folds along its body.
🔍 3. Ecology & Behavior
It feeds mainly on fish such as salmon, herring, and cod, as well as squid, shrimp, and crabs, capturing prey by suction. Usually seen in pods of 2–10, it gathers by the hundreds or thousands during summer migrations and gives birth in shallow estuaries.
🇰🇷 4. Connection to Korea
It is listed as 'Huindol-gorae' (Korean name) on the National List of Species of Korea, where it is recorded as potentially occurring throughout Korean waters.
