Mammal Species

Have you ever thought about what makes mammal species different from other vertebrates?

If not, I'm sure that you have noticed the differences between a crocodile (which belongs to the vertebrate class reptilia) and an elephant.

Being a mammal myself, I have always found this particular class of vertebrates very interesting.

Mammals have certain characteristics that differentiate them from other vertebrates.

Some of these characteristics include hair or fur, the ability to maintain a constant body temperature, and the production of milk.

To learn more about the characteristics that differentiate mammal species from other vertebrates, see Mammal Species.
