What are anatomical adaptations?

Anatomical adaptations are physical features that help an organism survive and/or reproduce in its environment.


For example, the thick fur of arctic foxes is an anatomical adaption that keeps it warm in a cold environment, helping it to survive.

What are physiological adaptations?

What is the purpose of camouflage in animals?

Camouflage is the outer colour and/or pattern of an animal that allows it to blend into its environment, making it harder for predators and/or prey to spot it.


This helps it survive and/or obtain food, leading to selection of this trait over generations.
