camouflage

Many other animals use camouflage -- colors, textures, or patterns that help them blend in with their environment. Some animals, like the flounder, can change to blend in with their environment, another form of camouflage. Animals use camouflage in different ways, but one thing is certain: it helps animals survive.

Definition: a color, pattern, or texture that helps an animal blend into its environment
Purpose: to hide from predators and prey
Examples: a zebra's stripes, a grasshopper's grassy-green color, a dolphin's bluish-gray skin
