Animal X-Rays

Real x-rays of mammals, reptiles, fish, amphibians and birds, printed on clear heavy-duty plastic — hold one to a window and look straight through a python.

There's a matching photo card for each, so your child sees the animal and then sees inside it. The featured creatures include a chameleon, crocodile eggs, a green iguana, a python, a diamondback and more.

The guide covers habitat, distinctive features and group type for each. Age 4+.
