White skin of belugas enables them to blend in with Arctic and sub-Arctic ice.
Typically, whales have a life expectancy of around 30 years.
Belugas produce up to 11 distinct sounds, including chirps, whistles, cackles, and squawks.
The bump on a beluga's head, known as a melon, changes shape depending on the sound emitted.
Unlike other whales and dolphins, belugas can turn their heads.
Belugas are highly sociable, forming groups averaging around 10 individuals.
They use their teeth not for chewing but to grasp prey, which they then swallow whole.
