Synopsis The resistance time of ammocoetes ofGeotria australis was related to the time of emergence from the substrate. The incipient lethal temperatures of animals acclimated at 5, 15 and 25° C were 27.3, 27.5 and 28.2° C respectively, the ultimate incipient lethal being 28.3° C. This value, which is similar to that of Northern Hemisphere lampreys such asLampetra planeri, almost certainly accounts for the restriction of this species to the southernmost rivers in Western Australia.
