Unbelievable Encounters: Frozen Humpback Whales and Tail Sailing

A video captured the rare phenomenon of a humpback whale engaging in "tail sailing," where its tail is perfectly poised above the water's surface. This behavior, observed in female whales with calves, could be a way for mothers to rest while their calves swim nearby. It is also possible that the whale is cooling down, as the tail contains high levels of blood vessels that could benefit from evaporative cooling. The exact reasons for tail sailing are not fully understood by scientists.
