Shrewlike rat
The shrewlike rats, genus ''Rhynchomys'', also known as the tweezer-beaked rats are a group of unusual Old World rats found only on the island of Luzon in the Philippines. They look a great deal like shrews and are an example of convergent evolution. Shrewlike rats evolved to be vermivores (worm-eaters) and insectivores feeding on soft-bodied invertebrates associated with leaf litter. ==Characteristics== The snout and rostrum are very long. Eyes are small. Head and body is 18.8–21.5 cm with a tail 10.5–14.6 cm (Nowak, 1999). Only two molars are present; these are small and peg-like. Incisors are described as needle-like and mandibles as delicate (Nowak, 1999; Balete et al., 2007).
