Mammal
Warm-Blooded Feature
Mammals are warm-blooded, which means they maintain a constant body temperature regardless of the environment.

Even in cold water, dolphins, which are mammals, stay warm.
Fur or Hair
All mammals have some form of fur or hair, although it may not be obvious, like in whales.

Even though hippos look hairless, they are mammals and have fine, thin hairs.
