What makes us mammals do we follow the basic rules?
Do we have some kind of coat like wool, fur... or hair? Are we warm blooded, have four limbs, breathe air, have a skeleton and drink our motherís milk when weíre babies?
Well, what about other mammals?
Why isnít a bird a mammal?

Or how about a fish? Is a spider a mammal Ė if not why not?

What groups do these other animals come from? Whatís an amphibian? And how about a reptile? What do all reptiles have in common?

Use the mammal rules (in the fact section) and design a brand new mammal.
