Abstract

The resistance time of ammocoetes of Geotria 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 as Lampetra planeri, almost certainly accounts for the restriction of this species to the southernmost rivers in Western Australia.
