Camouflage most developed in smaller animals (bigger animals have other way of defending themselves) Having camouflage on you means you"re bearing the coloration of your environment. Animal has to stay still (called being cryptic) Every habitat has general patterns (camouflage matching these patterns is called background matching i. e. grasslands and cattail marshes have vertical lines from the tall grass/cattails. Animal in this area would want vertical stripes to camouflage). i. e. forest floors are discolored with light and dark spots.
