The beluga whale is a white whale that primarily lives in the Arctic. Its name comes from the Russian word for white. In size, the average 14-16 feet (males) with a maximum length of 20 feet and 13-14 feet (females), with a maximum length of 17 feet. They weigh in the 3000 to 3,300 pound range.
Belugas can nod and turn their heads, unlike most other whales whose neck vertebrae are fused. They also don’t have dorsal fins, which allows them to go under the ice more easily.
About 20 years ago I got to see one face-to-face in the Long Island Aquarium—lovely! See if this video clip makes you smile.
