A captive hermit crab's life span depends on how well he's cared for. Jeffrey Hamilton/Digital Vision/Getty Images. If the wild hermit crab is fortunate enough to live his life in his natural habitat, he can live up to 30 years. A crab in captivity may have a much shorter life, not even reaching 1 year.
Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a single pair of chelae (claws). Crabs are found in all of the world's oceans, while many crabs live in fresh water and on land, particularly in tropical regions. Crabs vary in size from the pea crab, a few millimetres wide, to the Japanese spider crab, with a leg span of up to 4 metres (13 ft). About 850 species of crab are freshwater, terrestrial or semi-terrestrial species; they are found throughout the world's tropical and semi-tropical regions.
