Title: Energetic cost of feeding on different kinds of prey for the lizard Chalcides ocellatus
Author: Grimmond, N.; Preest, Marion; Pough, F. Harvey
Abstract: 1. Skinks (Chalcides ocellatus) used 50% more energy to crush and swallow hard-bodied insect prey (Tenebrio molitor beetles) than medium- and soft-bodied prey (Tenebrio molitor larvae and Manduca sexta larvae, respectively). 2. Even for beetles, however, the energy cost of prey handling was no more than 1% of the energy assimilated. 3. Differences in handling times are probably more important than differences in energetic costs in determining the desirability of different types of prey.
