The limb regenerative capacity of three species of Japanese anuran Rhacophoridae was investigated in postmetamorphic froglets and adults. In all species the limbs amputated at zeugopodium showed regenerative growth. In Rhacophorus schlegelii and Rh. arboreus most of the young froglets regenerated their limbs well in the rod- and palette-shapes. However, the rate of regeneration decreased with age, and the limbs became non-regenerative or formed only cone-shaped growths when they were in mature adults. The limbs of adult Rh. buergeri exhibited cone- and rod-shaped regenerates. The regenerates of these three Rhacophorus were heteromorphic and histologically consisted of well developed muscle and cartilage surrounded by connective tissue and skin. At the tips of these regenerates the epithelia showed differentiation into digital pads. On the basis of the results obtained, the relation between the body size and age and the regenerative capacity was discussed.
