Leaf-nosed bat rounded tips, range in body size from 4 cm to 13.5 cm and a wingspans of up to 90 cm or more. Like other bats, leaf-nosed bats are nocturnal foragers that use echolocation to locate food sources, though the food sources they are locating vary between species. Many bats in family Phyllostomidae appear to have limited reliance on echolocation, likely because frugivorous bats do not need to quickly identify flying insects like many other bats. Instead, species of leaf-nosed fruit bats appear to use scent to identify their preferred food sources. When they are not foraging, leaf-nosed bats roost in
Shrew orientation. In contrast to bats, shrews use echolocation only to investigate their habitats rather than additionally to pinpoint food. Except for large and thus strongly reflecting objects, such as a big stone or tree trunk, they probably are not able to disentangle echo scenes, but rather derive information on habitat type from the overall call reverberations. This might be comparable to human hearing whether one calls into a beech forest or into a reverberant wine cellar. The 385 shrew species are in 26 genera, which are grouped into three living subfamilies: Crocidurinae (white-toothed shrews), Myosoricinae (African shrews) and Soricinae (red-toothed
