A sea urchin's exoskeleton, known as a test, is quite hard and rigid due to its composition of calcium carbonate. This structure provides protection against predators and environmental factors. The test is also covered with spines, which add an additional layer of defense and help in locomotion. While it is sturdy, the test can be broken under sufficient force, but it remains a strong protective barrier for the sea urchin.
A skeleton that is found on the outside of a body is called an exoskeleton. These can also be manmade objects that assist humans. Exoskeletons have been developed to help paralyzed individuals to walk. They have also been developed to help increase the strength of an individual, allowing that individual to lift weight that is far beyond the capability of a normal being.
