than previously assumed. Kinosternon leucostomum was an omnivorous generalist in both populations studied. In one lake, in which Staurotypus was absent, the quantity of animal prey consumed by Kinosternon was significantly higher than in the other lake in which Staurotypus also occurred. The population of Kinosternon consuming more animal prey grew faster and larger, and had larger clutches of larger eggs. Sexual dimorphism of head size in Kinosternon was not related to dietary differences in the populations studied.
