The shrew-faced ground squirrel (Rhinosciurus laticaudatus) is a specialized rodent native to the Sunda Islands that has evolved to feed primarily on earthworms and insects.12

To capture its prey, this species utilizes its greatly elongated snout and a long tongue. Unlike many other ground squirrels that rely on powerful incisors for gnawing, the shrew-faced ground squirrel possesses weak incisor teeth, reflecting its specialized diet and foraging method.12
