Popis:	Calcium bodies are specialized organs of terrestrial isopod crustaceans (woodlice) in the family Trichoniscidae. These organs are epithelial sacs that contain an extracellular matrix, mineralized with calcium salts. Recent studies have demonstrated that the mineral content of these organs changes periodically in relation to molt, the process in which crustaceans shed their old exoskeleton and form a new one. During the preparation for molt, minerals are deposited in the calcium bodies and are resorbed during and shortly after molt [1, 2]. As the crustacean exoskeleton contains large amounts of calcium carbonate and calcium phosphate [3], calcium bodies may function as reservoirs that allow woodlice to temporarily deposit minerals from their exoskeleton before molt and mobilize it after molt, when great amounts of calcium are needed for the mineralization of the new exoskeleton.
