Exoskeletons contain chitin; the addition of calcium carbonate makes them harder and stronger. ... These structures are composed of chitin and are approximately six times stronger and twice the stiffness of vertebrate tendons. Similar to tendons, apodemes can stretch to store elastic energy for jumping, notably in locusts.
