There is a fierce contest in the animal world for survival. In each species the most fit have the best chance to feed, survive and pass their adaptive genes on to their offspring. One adaptation found in nature that aids survival is camouflage - the hunter can feed better if it is not seen by its prey and the prey can escape death if it is hidden or has some other form of protection. The question however becomes, what advantage is it for some organisms to have bright colors or strange shapes? The advantages of protection and deception afforded by these unexpected adaptations is answered in this lesson as students examine each slide trying to discover the mechanisms for survival, seen and unseen, in each.
