Why do stranded whales die even if they are returned to the water? It's not dehydration that kills them, but gravity. In the water, buoyancy supports the immense weight of a whale. However, when a whale is stranded on land, its organs begin to collapse under their own weight and even breathing becomes difficult.
Additionally, their dark skin absorbs heat from the sun and the thick layer of blubber, which is meant to keep them warm in cold water, acts like a heavy coat, increasing their body temperature.
Soon, the whale becomes dehydrated and its kidneys fail. This is why most whales return to the water die from their injuries. What's even stranger is that the rare whales that are successfully rescued often strand themselves again shortly after.
