What makes whales different from other animals?
In addition to large bodies, cetaceans have large brains—sperm whales currently hold the title for the largest absolute brain size on the planet . The brain to body size ratio is also important, and the only animals with a brain to body size ratio larger than whales are humans.

How are whales and dolphins different from other aquatic animals?

Why did whales lose their legs?
In findings to be published this week in the Proceedings of the National Academy of Sciences, scientists say the gradual shrinkage of the whales’ hind limbs over 15 million years was the result of slowly accumulated genetic changes that influenced the size of the limbs and that these changes happened sometime late in
Cetacean stranding, commonly known as beaching, is a phenomenon in which whales and dolphins strand themselves on land, usually on a beach. Beached whales often die due to dehydration, collapsing under their own weight, or drowning when high tide covers the blowhole.
What are whales afraid of?
Do whales ever drown?
If the whale took in water through its blowhole while underwater, it could drown. In fact, there are cases of whales that became stuck in shallow water drowning because the water was shallow enough to prevent the whale from swimming but deep enough to cover the whale’s blowhole and prevent it from breathing.
