The Russian term belukha, which means "white," is where the English name "beluga" is derived. White whales are another name for belugas. Beluga calves are often dark grey upon birth. As they become older, they gradually become lighter, and when they're fully grown, they develop the white colouring that adult belugas have. Because of their white colouring, belugas may hide from predators in the icebergs and ice floes of northern seas.
