Beluga Whales belong to the toothed or dolphin family of whales. Since they live mostly in arctic waters, adults are white and don't have the dolphintype dorsal fin as they spend a lot of time under ice sheets. Males are larger than females and can reach some 5 metres long. Calves can be greyer/browner. Thanks to Keith Wood for this photo of a young Beluga off Newfoundland.
