This name comes from the fact that adult beluga whales are mostly white, especially when they are mature.
While their name might be simple, the reasons behind their white color are a little more complex and still being studied by scientists! Some possible factors include:
* Camouflage: White may help them blend in with the ice and snow of their arctic environment.
* Protection: Their white color might help them reflect sunlight and stay cool in warm waters.
* Communication: Some scientists believe that the white color may help them communicate with each other.
* Evolution: As beluga whales have adapted to their environment over time, their color may have changed.
It's important to note that young beluga whales are actually born gray or dark gray, and they gradually turn white as they mature.
