Abstract

Among the reptiles, members of the families Colubridae and Elapidae have the largest adrenals (0.010 to 0.018 percent of total body weight). The values for the two species of Crotalidae are smaller (Sistrurus—0.0061 to 0.0081 and Crotalus—0.00139 percent). The adrenals of lizards are smaller than are those of the Colubridae (Basiliscus—0.0093 and Iguana—0.0074), those of a single specimen of Heloderma being lowest (0.0059 percent). The adrenals of the Testudinidae are similar to those of Heloderma (0.0057-0.0074 percent). These differences are probably gene controlled.
