Animal Defense Mechanisms
Animal Defense mechanisms are directly related to the Predator-Prey relationship which has lasted millions of years. Animals need to feel free to carry on with their normal activities like feeding, reproducing and so on, but it is always more difficult to do that when there is another animal always waiting to make you its dinner.
This brings fear to smaller animals that now need to develop ways to survive.
Animal Defense Mechanisms are therefore techniques that have been developed over a period of time that helps preys in their battles against predators.
