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.

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.
