The Brazilian shrew mouse (Blarinomys breviceps),[2] also known as the blarinine akodont,[3] is a rodent in the tribe Akodontini from the Atlantic Forest of eastern and southeastern Brazil.

[6] Overall, its specialized body structure lends itself to the animal's subterranean life, with broad forefeet and large claws for digging.

[7] It has a long snout that is used to find insects in the ground and highly developed jaw muscles that help to close the mouth quickly, as to avoid swallowing dirt.

[6] According to the International Union for Conservation of Nature's Red List of Endangered Species, the Brazilian shrew mouse is considered of least concern.

[1] However, some experts suggest that since the species is so difficult to find, data is insufficient to confidently label their conservation status.
