This Is Why Some Bats Have Hairy Tongues

Nectar-drinking bats possess hairy tongues, and now scientists reveal these hairs are designed to maximize how much sweet nectar the bats can guzzle. The South American Pallas' long-tongued bat, Glossophaga soricina, dips its long tongue in and out of flowers while hovering in mid-air, and the hairs on its tongue apparently helping it collect nectar that pools at the bottom of the blossoms.
