Spikes for protection from animals eating it Tough outer 'skin' so its hard for animals to eat
Spiders are arachnids, which means that they are animals with exoskeletons. Their "skin" is a hard outer coating that protects their soft inside bodies.
Crustaceans are animals that live in the Ocean. Their skin, is their outer-shell of a body, so it would be hard and thick.
Reptiles are animals that have dry skin. However, other animals can have dry skin as well. Though in other animals the skin must be treated to get rid of the dryness.
No, the reason for this is because some animals live in different environments therefore they need different skin for different things. Some animals that live in the jungle have skin that helps them camouflage themselves to prevent predators from hunting them, if they live in a hazardous area they are likely to have hard, rough skin to help prevent injury.
They have a green skin, like the leaves they live on. Besides that, their skin reflects the same wavelength as leaves, so they are hard to see for animals who can see in the dark -like snakes.
Animals who need to have moist skin are amphibians, such as frogs.
