Abstract
Regression analysis and analysis of covariance on linear measurements of body size (forearm length), head length (condylo-canine length), and length of maxillary toothrow showed significant differences among 245 species of bats in 12 families. The linear measurements of the 194 animal-eating species, namely those in the Emballonuridae, Vespertilionidae, Phyllostominae, Rhinolophidae, Nycteridae, and Megadermatidae, showed that species of bats with longer heads had longer maxillary tooth-rows. The data also showed that some animal-eating bats which are presumed to forage from continuous flight have proportionally shorter heads than species that use sally foraging. Molossids, species specialized for rapid, efficient flight, had longer heads than expected, whereas sally-foraging hipposiderids had shorter heads. I use the data to predict that head length in animal-eating bats affects the size of prey selected.
