Chameleon's Eyes
A Chameleon's eyes have a 360-degree arc of vision. It can rotate each eye independently of the other, and so, can see two directions at once.
Invisible Fish
The hatchet fish found only in the deep sea, has sides that are covered with large silver scales that act like mirrors, and two rows of light-producing organs on its underside. The effect is to make the fish invisible to its enemies.
Ancient Fireworks
Fire was first produced by striking together pieces of either flint or iron pyrites. These minerals give off sparks when they are hit with something hard. Later, flint and iron pyrite were both used to ignite gunpowder in ancient rifles.
