Vermivore
Vermivore (from Latin vermi, meaning "worm" and vorare, "to devour") is a zoological term for animals that eat worms (including annelids, nematodes, and other worm-like animals).[1] Animals with such a diet are known to be vermivorous.[2] Some definitions are less exclusive with respect to the diet, but limit the definition to particular animals, e.g. "Feeding on worms or insect vermin. Used of a bird."[3]
An entire genus of New World warblers has been given the name Vermivora.
One vermivore that may feed exclusively on worms is Paucidentomys vermidax, a rodent species of a type commonly known as shrew rats which was discovered in 2011 in Indonesia. The name, which can be translated as "worm-eating, few-toothed mouse", refers to the fact that they have only four teeth and may live exclusively on a diet of earthworms.[4] This reduced dentition in vermivorous mammals is said to be due to relaxed selectional pressure on dental occlusion.[5]
