Beluga whales, or Delphinapterus leucas, are among the most iconic whales of the Arctic.🐋
Nicknamed the “canaries of the sea,” they produce an incredible variety of clicks, whistles, and chirps used for communication and navigation. Their white coloration provides camouflage against sea ice, and their lack of a dorsal fin helps conserve heat while allowing them to swim easily beneath ice sheets. One of their most unique traits is their unfused neck vertebrae, which means they can turn their heads side to side and up and down, making them unusually agile compared to other whales.
Belugas are highly social, often found in pods that cooperate in hunting and calf care. They migrate with the seasons, moving into shallow estuaries in summer where they calve, molt, and rub against gravel or rocks to shed old skin. Ecologically, they are mid-level predators feeding on fish, squid, and invertebrates, and their health reflects the condition of Arctic marine ecosystems. Culturally, they hold deep importance for Indigenous peoples, who have sustainably relied on them for food and traditions for generations. Today, climate change, shipping noise, and shifting prey dynamics present new challenges, making belugas an important species to watch as the Arctic undergoes rapid transformation.
