Crocodylians being poikilotherms, are of interest because of their massive sizes, and how they respond to situations where behavioural thermal selection varies. The purpose of this study was to examine Tb trends in Crocodylus palustris, with respect to post-feeding, the impact of enclosure maintenance, how visitor numbers affected Tb, and variability within and between animals. The three subject animals comprised a group of 31 crocodiles, held in a natural pond. Hobo TM loggers were used to record deep body temperatures, which were inserted surgically into the peritoneal cavity of ten females. Prior to this, all animals were measured, weighed, and codes recorded. Crocodiles maintained a very narrow regime in temperature chosen, and rainfall did not result in an increase in Tb; minor increases in Tb were observed post-feeding, a decrease in Tb was observed on the Park’s day off. A major maintenance activity resulting in elevated Tbs for up to a week in all animals. Despite large deviations in female weight, Tb remained similar. Oscillation in Tb was similar, lower thresholds being at 0700 hrs, and peaking at 1700hrs.
