The mammal with the largest penis relative to body size is the fossa Cryptoprocta ferox. This civet-related, puma-resembling carnivore, endemic to the island of Madagascar, has a penis length of 17–20 cm, reaching to between its forelegs when full-sized, and a total head-to-tail length of 120–150 cm. This means that its penis is nearly one-sixth as long as this mammal's entire length.
