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
Animal echolocation mammals other than bats known to echolocate include two genera ("Sorex" and "Blarina") of shrews and the tenrecs of Madagascar. These include the wandering shrew ("Sorex vagrans"), the common or Eurasian shrew ("Sorex araneus"), and the short-tailed shrew ("Blarina brevicauda"). The nature of shrew sounds unlike those of bats are low amplitude, broadband, multi-harmonic and frequency modulated. They contain no ‘echolocation clicks’ with reverberations and would seem to be used for simple, close range spatial orientation. In contrast to bats, shrews use echolocation only to investigate their habitat rather than additionally to pinpoint food. There is evidence that blinded laboratory
