Predation is an interaction between species in which one species, the predator, kills and eats the prey. Snakes, such the one hidden inside the log in the picture here, are examples of predators. Snakes eat animal prey, including lizards, insects, or even larger animals, such as antelope. Since eating and avoiding being devoured are “prerequisites” to reproductive success, the adaptations of both preys and predators are refined through natural selection. Many predators have acute senses that allow them to locate their prey. Predators that chase their prey are usually fast and swift. Camouflage is a very common defense against predators.
