There are four basic types of camouflage:
Concealing Coloration- when an animal hides against a background of the same color (polar bears, snowshoe hare, and arctic fox with white fur living in the Arctic).
Disruptive Coloration- stripes, spots, or other patterns an animal uses to make it hard for predators to their body outline (zebras, leopards, tigers living in grasses).
Disguise- like concealing coloration but the animal blends in with their surrounding by shape and texture rather than color (lizards with bumpy skin, octopus mimicking coral, walking stick insect).
Mimicry- animals mimic the characteristics of unappetizing animals (insect mimicking a poisonous bug, caterpillar designed to look like a snake).
