Allometry and sexual dimorphism in the lung morphology of prairie rattlesnakes, Crotalus viridis viridis

Keogh, J Scott; Wallach, V


We quantified sexual dimorphism and allometric changes in the lung morphology of 160 juvenile and adult specimens of prairie rattlesnake, Crotalus viridis viridis, from a single population. In virtually all lung components, those of males are located more posteriorly than are those of females of the same body size. Males display a longer vascular component than females but there is no sexual dimorphism in size of the avascular component. Thus, males generally have longer lungs than do females...[Show more]
