Abstract

Endurance of juvenile Western Australian varanid lizards was compared with that of conspecific adults. Among adults, endurance generally increased intra-specifically with increasing body size. However, juvenile varanids have a higher than expected endurance. Possible causes for this heightened endurance are discussed, and probably result from a relatively high maximal metabolic rate, as has been previously described for juvenile varanids. Origins of relatively high metabolic rates are unknown, but may be caused by greater oxygen affinity of juvenile haemoglobin when compared to adult conspecifics.
