Brown long-tongued bat feeding
Brown long-tongued bat (Glossophaga commissarisi) that has just triggered a ripe sea bean flower (Mucuna holtonii) to fire pollen onto its rump. The sea bean's anthers and stamens are sized and shaped to effectively fire pollen onto the rumps of bats. Inflorescences hang below the surrounding foliage on 90-180 centimetres long stems known as peduncles that facilitate approaches by flying bats. Each inflorescence is about 12-18 centimetres in diameter and contains many buds with up to 8 flowers opening each night for approximately 6 weeks. A flower that is ready to be pollinated signals its readiness by raising its dish-shaped banner (the vexillum), adapted to strongly reflect echoes from many different directions. Bats normally ignore this flower until its banner has risen to a nearly vertical position. As flower firing is triggered, the bat is rewarded by receiving an average of 100 microliters of nectar (a relatively large quantity). Bats that subsequently visit already fired flowers get approximately 10-20 microliters of nectar. Each flower can fire only one time.
