Animal and plant adaptations and behaviours. Adaptations help organisms survive in their ecological niche or habitat; adaptations can be anatomical, behavioural or physiological. Anatomical adaptations are physical features such as an animals shape. Behavioural adaptations can be inherited or learnt and include tool use, language and swarming behaviour. Physiological adaptations include the ability to make venom; but also more general functions such as temperature regulation.
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.
