Since cardiovascular, respiratory, and metabolic systems of reptiles are affected by temperature, accurate measurements are of great importance in both captive husbandry and research. Ectothermic animals generally have core body temperatures close to ambient temperature but can differ from the immediate environment if they are using sunlight to thermoregulate. Many zoological facilities and exotic pet caregivers have begun using infrared temperature guns to assess ambient temperatures of reptile enclosures but there are currently few studies assessing the efficacy of these devices for measuring the body temperatures of reptiles. , (Galápagos land iguanas), and X hybrid are robust land iguanas endemic to the Galápagos archipelago. By comparing the infrared body temperature measurements of land iguanas against virtual simultaneous collection of cloacal temperatures obtained using a thermocouple thermometer, we sought to assess the efficacy of this non-invasive method. We found that internal body temperature can be predicted with a high level of accuracy from three external body temperature sites, providing a good non-invasive method that avoids the capture of animals.
由于爬行动物的心血管、呼吸系统和代谢系统会受到温度的影响，因此在圈养饲养和研究中进行准确测量都非常重要。变温动物的核心体温通常接近环境温度，但如果它们利用阳光进行体温调节，则可能与周围环境温度不同。许多动物园设施和外来宠物护理人员已开始使用红外测温枪来评估爬行动物饲养箱的环境温度，但目前很少有研究评估这些设备测量爬行动物体温的有效性。 （加拉帕戈斯陆鬣蜥）和X杂交种是加拉帕戈斯群岛特有的强壮陆鬣蜥。通过将陆鬣蜥的红外体温测量结果与使用热电偶温度计同时虚拟采集的泄殖腔温度进行比较，我们试图评估这种非侵入性方法的有效性。我们发现，可以从三个外部体温部位以高度准确性预测内部体温，从而提供一种避免捕获动物的良好非侵入性方法。
