You have just learned that the way a jaw is shaped relates to its function in eating. Here are some examples of how structural adaptations in other animals are related to certain functions.

• To avoid being spotted by other animals that might eat them—or by ones they might be trying to eat—some insects use different colors or patterns to blend in with their environment. This adaptation is called camouflage.
• To better survive in the dark, animals that are active at night have evolved various adaptations. Owls have excellent night vision. Bats send out high-pitched sounds to find insects. And foxes and rabbits have large ears that improve their sense of hearing.
• To remain active in winter, many animals such as foxes and snowshoe hares have large furry feet that keep them from sinking into deep snow.
