How do whales stay warm?

Mammals that have adapted to live in cold waters—such as polar bears and whales—can stay warm largely because of their blubber, a thick layer of blubber. The blubber is evenly spread over much of their body, just as the shortening in this activity covered the surface of your finger in a thick layer.

Why are marine animals cold blooded?

Like reptiles and amphibians, fish are cold-blooded poikilothermous vertebrates —meaning they get their body temperature from the surrounding water. … Temperature also affects metabolism and metabolic processes occur quicker in warmer water. This also adds to the amount of oxygen fish require.

Is whale a fish or mammal?

Why is a whale not a fish?

Whales are warm blooded, which means they keep a high body temperature that does not change in the cold water.
