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
Evolution of cetaceans "Caperea marginata") all have derived characteristics presently unknown in any cetothere and vice versa (such as a sagittal crest). The adaptation of echolocation occurred when toothed whales (Odontoceti) split apart from baleen whales, and distinguishes modern toothed whales from fully aquatic archaeocetes. This happened around 34 million years ago in a second cetacean radiation. Modern toothed whales do not rely on their sense of sight, but rather on their sonar to hunt prey. Echolocation also allowed toothed whales to dive deeper in search of food, with light no longer necessary for navigation, which opened up new food sources. Toothed whales
