Temperature may significantly affect chemoreception. For instance, electrical responses to amylacetate delivered to olfactoiy receptors of a tortoise, Gopherus polyphemus, were little affected by air temperatures between 20 and 30 °C at the nares but changed considerably above and below that range. Up to - -35 °C and down to -1-10 °C, the olfactory response was a monotonic slowly decreasing function of temperature (Tucker, 1963 see also Grundvig etal., 1967).

Tortoises can distinguish sex by chemical cues. A mixture of fatty acids has been extracted from the chin glands of males of several species of Gopherus. Applied to the head of a plaster tortoise, these fatty acids trigger head bobbing in females, a component of courtship, while males rammed the models in an aggressive manner (Rose, 1970).
