What's an adaptation?
An adaptation is a change or the process of change that an organism makes in order to help itself survive in its environment. There are three main kinds of adaptations: physiological, anatomical, and behavioral.
What's a physiological adaptation?
A physiological adaptation is one within the internal organs of an organism. It usually occurs in response to an environmental stimulus. Physiological adaptations help organisms cope with their changing environments.
A toucan's bill is full of small blood vessels and it's uninsulated. This allows for the beak to be an easy way to dump inner heat. When toucans are flying, during which they can create 10 to 12 times as much heat as they do when they are resting, their beaks can increase temperature by up to 6 degrees Celsius. When they sleep, their body temperature decreases so as to conserve energy, and their beaks heat up. Thanks to this adaptation, birds are able to maintain their body temperature.
What's an anatomical adaptation?
See other animals below that use camouflage.
A gecko disguises itself by hiding in a tree the same color as its skin.
The owl's feathers are the same color and texture as the tree.
A frog that looks like a leaf (or a rock) is camouflaged by its surroundings.
