Beluga whales, also known as white whales, are a distinctive and charismatic species of marine mammal. They are easily recognized by their pure white coloration and rounded melon-shaped forehead. Belugas are found primarily in the Arctic and sub-Arctic waters of the Northern Hemisphere, where they prefer shallow coastal areas and river estuaries. Beluga whales are members of the family Monodontidae, which also includes the narwhal. They are characterized by their lack of a dorsal fin, which is an adaptation to their Arctic habitat as it reduces heat loss in cold waters. Belugas have a streamlined body and powerful flukes that enable them to swim quickly and maneuver easily in icy waters. Beluga whales are highly social animals and often form large pods of up to several hundred individuals. They communicate using a complex series of clicks, whistles, and chirps, which are used for echolocation, social interactions, and hunting. Belugas feed primarily on fish, but they also consume squid, crustaceans, and other invertebrates. Beluga whales have a unique cultural significance to many Indigenous communities in the Arctic. They have been hunted for centuries for their meat, blubber, and skin, which were used as food, fuel, and clothing. Today, beluga whales are protected by international law, and hunting is regulated by quotas and permits. In summary, Beluga whales are a unique and fascinating species of marine mammal found in the Arctic and sub-Arctic waters of the Northern Hemisphere. They are known for their pure white coloration, rounded foreheads, and lack of dorsal fins. Belugas are highly social animals that communicate using complex vocalizations and form large pods for social interactions and hunting. They have a unique cultural significance to many Indigenous communities in the Arctic and are protected by international law today.
