By Jennifer Kennedy. Definition: An adaptation is a physical or behavioral characteristic that has developed to allow an organism to better survive in its environment.Adaptations are the result of evolution, and may occur when a gene mutates, or changes by accident.xamples: One physical adaptation used in the intertidal zone is a crab's hard shell, which protects it from predators, drying out and being crushed by waves. A behavioral adaptation in the oceans is the use of loud, low-frequency calls by fin whales to communicate with other whales over great distances.
