Many types of animals are insectivores, meaning they live primarily off insects and other invertebrates. Many species of birds, fish, reptiles and amphibians fall into this group, as well as a semi-diverse group of mammals. Most insectivorous mammals are small, but some grow to be quite large. The geographic range of insectivores spans the globe, with many species native to North America.
