Arthropods have an exoskeleton and segmented bodies, they include ocean and land creatures.
The external covering of an arthropod is referred to as an exoskeleton. In some arthropods (water varieties) the exoskeleton is composed mostly of calcium carbonate. In land varieties of arthropods, such as insects, their exoskeletons are made of a material know as chitin.
what variation would help a land survive in long lasting droughts
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. http://edhelper.com/ReadingComprehension_54_61.html
