Bats in the old World family Pteropodidae have very large eyes and excellent eyesight in low light, but do not use echolocation. Within the Pteropodidae family, bats in the genus Pteropus are known as flying fox because their face and ears resembles a fox or small dog. The bats found on Guam are Pteropus mariannus, locally called fanihi or fruit bats.
