Abstract
Scales on the hairs of pollinating bats spread out at an angle to the main hair shaft. In contrast, the hairs of most bats not associated with plants are relatively smooth. Both megachiropteran and microchiropteran flower‐feeding bats show this divaricate scale structure which may aid in the collection of a heavy coating of pollen. Some of the pollen is transferred to subsequent flowers, but most is groomed from the fur and ingested as the only reliable nitrogen source for the bat.The tongues of nectar‐feeding bats also show structural modifications which allow efficient uptake of the carbohydrate fraction of the diet.Structural specializations of the hairs and tongue are analogous to those seen in other nectar‐feeding animals.
