Abstract     
Testudinidae Gopherus agassizii Sauromalus obesus Seven species of desert vertebrates lívíng in winter-rainfall deserts were compared and contrasted with respect to the means they use to survive a year in the field. The two plant-eating reptiles, chuckwalla lizards and desert tortoises, both husband rheir water and energy budgets remarkably well, but chuckwallas have opted for precise osmotic and body fluid volume regulation, which restricts them to feeding only on green, moist vegetation in spring, whereas tortoises tolerate wide swings in their osmotic and fluid balance, and can thereby drink rainwater and eat dry vegetation during summer and autumn.
