Welcome to the World of Beluga
Belugas
Delphinapterus leucas
Also known as: White whale
Average lifespan: 35–50 years
Primary habitat: Arctic and subarctic coastal waters
Geographic range: Arctic Ocean and surrounding northern seas
Overview
Beluga whales are small, highly social whales known for their white color and wide range of vocal sounds. Often called the “canaries of the sea,” they rely on communication and cooperation to survive in icy waters. Their flexible necks and expressive faces make them one of the most recognizable whales.

Conservation
Belugas play an important role in Arctic and sub-Arctic ecosystems by helping regulate fish and invertebrate populations and serving as indicators of ocean health in icy coastal waters. While some populations are stable, others are threatened by climate change, shrinking sea ice, pollution, underwater noise, ship traffic, and habitat disturbance—especially in river estuaries. Conservation efforts focus on protected habitats, stricter shipping and noise regulations, pollution control, and long-term monitoring to safeguard vulnerable beluga populations as Arctic environments rapidly change.​
