Why do whales die out of water?

Cetacean stranding often leads to death due to dehydration. Whales have an incredibly thick layer of insulating blubber. Without the water to keep them cool, they overheat and lose too much water via evaporation from their lungs.

Could a whale live in a lake?

Whales migrate based on the seasons and their needs. … To access their food, they may find themselves in brackish water (water with a salt content lower than that of sea water), or even in freshwater. Some species adapt to changes in water salinity.

Why do whales explode when they die?

But why do they explode, exactly? When a whale dies in the wild, it sinks to the ocean floor where it’s eventually scavenged by communities of sharks, fish and tiny bone-eating worms. … Gas builds up inside the whale as its stomach contents decompose — but due to its thick, tough blubber and skin, it can’t be released.

Do whales sleep at night?
