Look at this picture. It is an owl. We can see the following facts about owls:
Owls‘ eyes are useful for seeing well at night;
Their feathers have soft edges that allow them to fly silently;
Owls’ sharp
claws are useful
for hunting.
Each of these things is an adaptation.

An adaptation is a characteristic that helps a living thing survive.
Physical Adaptations
Some adaptations have to do with an animal’s body or a plant’s structure. These are Physical Adaptations.
For example, the thick, waxy stem of a cactus allows the plant to store water in the desert.
Behavioral Adaptations
Some adaptations have to do with an animal’s acts or behaves. These are Behavioral Adaptations.
For example, Most birds migrate to find food and a place to lay eggs.
Let’s see some adaptations and answer what kinds of adaptations they are.
porcupine uses its quills for defense.
They are both physical adaptations.
2. A turtle’s shell protects it from being eating by other animals.
1. Almost all owls hunt at night.

2. Animals hibernate to conserve energy and avoid a food shortage.
Each living thing uses its adaptations for survival.
