Beluga Legs
Appendages are not present on whales, sharks, and other sea creatures. On the other hand, the beluga appears to be an exception with what appear to be legs. This drawing prompted a feeding frenzy among researchers attempting to figure out the purpose of the symmetrical bone-like features in the tail.
Even though they cannot be classified as legs, they are known as blubbers. They’re a row of fatty insulations that beluga whales build on their side. Evolution backs up the notion that belugas may have descended from land-dwelling creatures that roamed the Earth over 50 million years ago. It implies they had legs before.
