What teeth and eyes tell us

By Gina Jack and Eileen Stegemann

A Predator's equipment

Coyotes (see illustration above) have forward-facing eyes for binocular vision, canines for puncturing flesh, and heavy carnassials teeth for crushing bones.

Peripheral Vision

Drawing of a rabbit showing how the position of its eyes increases peripheral vision
A rabbit has eyes on the side of its head
to see danger approaching from almost
any direction.

Peripheral vision is what you see to the sides while you're looking straight ahead-the edges of your eyesight. How far behind you can you see? How does this compare with the rabbit, pictured to the left?

Check your peripheral vision
A diagram of how to test your peripheral vision

1. Hold your arms straight out in front of you with your thumbs pointing upwards.
2. Keep looking straight ahead while you slowly move your arms out to the sides.
3. Stop moving your arms when you can no longer see your thumbs from the corners of your eyes.
