Taxonomy and etymology

The tube-lipped nectar bat was first described in 2005.[2] The species name fistulata is derived from the Latin word fistula, meaning "tube". It refers to the bat's lower lip, which extends 3.3–4.8 mm beyond the upper lip and is rolled into a funnel shape. The exact function of the tube-lip is unknown.

Description

The bat has the longest tongue (8.5 cm) relative to its body size of any mammal. Its tongue is 150% the size of its overall body length. By convergent evolution, pangolins, the giant anteater (Myrmecophaga tridactyla), and the tube-lipped nectar bat all have a tongue that is detached from their hyoid bones and extend past the pharynx deep into the thorax.[3] This extension lies between the sternum and the trachea.

Biology and ecology

Despite its exceptionally long tongue, the tube-lipped nectar bat has a varied diet that includes nectar, pollen, and insects. This arrangement is possible due to its short jaw. The base of the tongue is in the bat's rib cage.[4] One plant, Centropogon nigricans, with its 80– to 90-mm-long corollae, is pollinated exclusively by this bat.
