Anatomy

__The Outside...__


This is what a platypus looks like from the outside. It has a bill like a duck, tail like a beaver, and webbed feet. Its fur can be any shade of brown. A male platypus is usually about 20 inches long, and weighs about 3.7 lbs. A female platypus is usually about 17 inches long and weighs about 1.9 lbs.

__The Inside...__
As you can see, the platypus is a vertebrate animal, which means it has a backbone. Instead of teeth, they have grinding pads to grind up the food they catch.
