Beluga whales

The mysterious beluga whale is one of our park’s most sociable animals. Born dark grey, their signature white color is actually cool camouflage belugas develop by maturity, allowing them to swim in the waters of their icy arctic homes.

Charicteristics
Nicknamed “sea canaries” by mariners, belugas are often heard before seen thanks to their unmistakable vocalizations. Instead of dorsal fins, they have a low dorsal ridge that lets them easily swim beneath thick ice sheets and find breathing holes; a pretty cool adaptation essential to life in one of the coldest regions of the globe.

Section heading
The beluga or white whale, Delphinapterus leucas, is an Arctic and sub-Arctic Cetacian. This marine mammal is commonly referred to simply as the beluga or sea canary due to its high-pitched twitter. Using the term "white whale" to refer to belugas is, in the strictest sense, erroneous, as the term "whale" is usually applied to the  baleen whales and not to toothed cetaceans which belong to the suborder odontoceti, which also includes dolphins and porpoises."
