Honduran fruit-eating bat Neotropical bats, which typically range from 10-85 g. It displays the characteristic lack of tail and narrow patagium seen in fruit bats, and also has a very densely furred uropatagium, which distinguishes A. hirsutus and A. inopinatus from many other species in the genus. Like most bats, they are nocturnal, roosting during the day, and use echolocation for navigation at night. The bats are in the family Phyllostomidae, also referred to as the New World leaf-nosed bats. This group tends to have distinct pointed, or "leaf shaped" snouts which assist them in echolocation. The Honduran Fruit Eating bat has a
Animal echolocation naturalist Louis Jurine repeated Spallanzani's experiments (using different species of bat), and concluded that when bats hunt at night, they rely on hearing. In 1908, Walter Louis Hahn confirmed Spallanzani's and Jurine's findings. In 1912, the inventor Hiram Maxim independently proposed that bats used sound below the human auditory range to avoid obstacles. In 1920, the English physiologist Hamilton Hartridge correctly proposed instead that bats used frequencies above the range of human hearing. Echolocation in odontocetes (toothed whales) was not properly described until two decades after Griffin and Galambos' work, by Schevill and McBride in 1956. However, in 1953, Jacques
