Biometric data of a male Chelonoidis denticulata (specimen No. 7); weights are rounded to two decimal places. Compared with adult South American Yellow-footed Tortoises, weight and volume increase at a much more rapid pace in juvenile specimens (comp. Tab. 6). Sexes could be identified from an age of about twelve years (+1/–2) when the carapace lengths of the tortoises had reached some 32 cm.
