(females). The Hammer-headed Fruit Bat is the largest and most sexually dimorphic (fruit) bat in Africa, with greatly enlarged muzzle. Remarkably, males are almost twice as heavy as females. Head is noticeably hammer-shaped in males, in which muzzle is greatly expanded and ends in flat, fleshy plate formed by both lips; muzzle of females is less developed; and tongue is large, with expanded tip and backward-pointing papillae, well adapted for rasping fruit. Eyes are large; irises are brown. Ears are blackish brown and triangular, with anterior and posterior basal white ear patches, which can be inconspicuous in some individuals. Adult males do not have epaulettes, but they do have mantle of long, woolly, pale grayish brown hairs; dorsum is generally sepia-brown, sometimes with grayish brown tinges, changing to rusty brown on rump and legs; pelage is soft and mid-dorsally

. Skull is larger and more robust than in any other African bat; basicranial axis is deflected; rostrum is huge, relatively long, and laterally compressed, greatly elevated above dental line, especially in males; premaxilla and nasals are marked with prominent bumps; sagittal crest is moderately to well developed; zygomatic arches are moderate; and interdental palate is concave from left to right and from front to back. There are 10-11 palatal ridges; ridges 1-2 are very thick; ridge 3 is very thin; three interdental ridges are wide laterally and narrow medially; ridge 4 is partially post-dental, weakly serrated with wide cushion-like pad near each edge and shallow concave center; ridge 5 is similar to ridge 4 but more strongly serrated and less shallow in center; ridges 5-6 are thin and serrated; irregular post-dental ridges are also present that might or might not be divided; and post-dental palate lacks raised sides. Dental formulais12/2,C1/1,P 2/3, M 1/2 (x2) = 28. Supernumerary premolar can be present in upper tooth row; P* and molars are distinctly lobed. Larynx of males is extremely enlarged, up to one-half the vertebrate column and fills up most of thoracic cavity. Pair of inflatable pharyngealair sacs form resonating chambers that produces extremely loud honking calls. Chromosomal complement has 2n = 36 and FNa = 68, with 13 pairs of large to small metacentric or submetacentric and four pairs of medium-sized submetacentric or subtelocentric autosomes. X-chromosome is submetacentric or subtelocentric, and Y-chromosomeis possibly small subtelocentric.

. Otherfruits are eaten from at least eleven plant genera and ten families, along with many cultivated fruits. Fruits are taken in the mouth and carried to a nearby tree, where they are squeezed for juice. Observations of Hammer-headed Fruit Bats attacking and eating chickens, scraps of meat, and skinned carcasses of small birds are questionable. The Hammer-headed Fruit Bat drinks by scooping water directly into his mouth while flying close to water or indirectly by wetting fur while skimming over water and licking water from fur.

. A female selects a male and lands besides him, and they mate. Afterward, the female leaves, and the male resumes his display until 22:00-23:00 h. Up to 70% of males might not copulate during mating season, and only ¢.6% of males are involved in ¢.79% of copulations. Gestation lasts 5-6 months, and births take place in dry seasons: December-February and June-July. Sex ratio at birth is 1:1. Females are sexually mature at c.6 months old (even before reaching full size at ¢.9 months); males become sexually active at c.18 months old.

During the day, males and females generally roost in large trees. Early in the morning, they defecate at their roost site and then rest or sleep until sundown. During the day, they do not make noises, groom, or squabble, and males, which generally rest on the outside of the group, do not approach females. In the evening, individuals wake, start grooming themselves, and leave individually to start foraging or fly to lek sites. Roostsites are

Other roost types exceptionally include undergrowth, rocks, and huts, and there is an unconfirmed record of a cave. Males compete in leks by beating their wings and especially by making loud honking sounds (c.2-3/second). These calls attract females.

Classified as Least Concern on The IUCN Red List. The Hammer-headed Fruit Bat has a wide distribution and presumably large population. It is unlikely to be declining fast enough to be listed in a higher category. It is threatened by hunting for food, and it is also persecuted for its noisiness at leks during mating seasons.
