Why do the eyes of animals tell us a lot about them?
Most animals — and Man- have two eyes. Some animals have compound eyes- but there are also animals with one eye, three eyes, and even eight eyes!
The freshwater crustacean cyclops has just one black or red eye in the middle of its head. The tuatara, which lives only in New Zealand, has three eyes. Some spiders have eight eyes that give them a near 360-degree view of the world.
Predatory mammals have eyes in the front of their heads, with powerful eye muscles.
An animal that is preyed upon by many enemies has its eyes out on the sides of its head, and each eye has its own field of vision. In fact the eyes of an animal tell the story of the creature's life, its sources of food, its habits, Its fears, and the history of its species.
