An insectivore is a carnivorous plant or animal that eats insects.[1] An alternative term is entomophage,[2] which also refers to the human practice of eating insects.
The first insectivorous vertebrates were amphibians. When they evolved 400 million years ago, the first amphibians were piscivores, with numerous sharp conical teeth, much like a modern crocodile. The same tooth arrangement is however also suited for eating animals with exoskeletons, thus the ability to eat insects is an extension of piscivory.[3]
At one time, insectivorous mammals were scientifically classified in an order called Insectivora. This order is now abandoned, as not all insectivorous mammals are closely related. Most of the Insectivora taxa have been reclassified; those that have not yet been reclassified remain in the order Eulipotyphla.
Although individually small, insects exist in enormous numbers – they number over a million described species[4]:1958 and some of those species occur in enormous numbers. Accordingly, insects make up a very large part of the animal biomass in almost all non-marine, non-polar environments. It has been estimated that the global insect biomass is in the region of 1012 kg with an estimated population of 1018 organisms.[5]:13 Many creatures depend on insects as their primary diet, and many that do not (and are thus not technically insectivores) nevertheless use insects as a protein supplement, particularly when they are breeding.[6]
