All arthropods have an external skeleton- an exoskeleton. Some exoskeletons are hard, like that of a lobster. It is made out of chitin. Some exoskeletons are leathery, like that of a caterpillar. Both types are waterproof. The exoskeleton keeps the animal from drying out. This characteristic gave arthropods the ability to live on land.
