FAQ
Frequently Asked Questions
A dolphin is a mammal. It breathes air, gives birth to live young, and feeds them milk, despite living in the ocean.
The main differences are that mammals are warm-blooded, have hair or fur, and feed their young milk. Reptiles are cold-blooded, have scales, and do not produce milk.
Yes, biologically, humans (Homo sapiens) are classified as mammals. We share the key mammalian traits: we are warm-blooded vertebrates with hair, and human females have mammary glands to feed infants.
A bat is a mammal. It is the only mammal naturally capable of true and sustained flight. Bats have fur, give birth to live young, and feed them milk.
