Age related changes in the digestibility of tendon collagen of the garden lizard, Calotes versicolor, were traced using type I collagenase from Clostridium histolyticum. Collagen from older lizards showed less susceptibility for collagenase digestion than the younger lizards suggesting increased number of cross-linkages comparable with mammals.
