The name "hammer-headed bat" refers to the distinctive head shape possessed by the male bat, which is box-like and elongated, creating a large resonant space to enhance their calling sound. This unusual head shape is a result of the unique mating pattern in this bat species. This uniqueness makes this animal stand out among the "Megabats" family, which is the largest family in the African continent. The following is a description of the hammer-headed bat quoted from livescience.com on (8/5).

Name: Hammer-headed bat (Hypsignathus monstrosus) Habitat: Lowland forests in West and Central Africa Food: Fruits, including figs, bananas, guavas, mangoes, and flies The bat with a head resembling a hammer is one of the bat species that practices a lek mating pattern. This pattern is like a competition where around 150 males gather twice a year to attract female attention with loud honking sounds and wing movements.

On the other hand, to attract their partner, females do not need a large head, so they have a slimmer snout like a fox. Their body size is also smaller, weighing about half of the males, which is around 0.5 pounds (230 grams), compared to 0.9 pounds (420 g), and their length is about 8 inches (20 cm), compared to males that can reach up to 11 inches (28 cm).

In 1968, research noted observations of bats feeding on bird carcasses and attacking chickens to suck their blood in the Gabon area. An observer named Harry Andrew Beatty, who was also a collector of herpetology specimens, twice saved chickens attacked by "Hypsignathus" at night, as recorded in the research. An additional interesting fact about the hammer-headed bat is its habit of wrapping its wings around its nose while sleeping.
