The hammer-headed bat is the largest bat in mainland Africa. [12] Males have wingspans up to 90.1 cm (2.96 ft), [ 13 ] and all individuals have forearm lengths exceeding 112 mm (4.4 in). [ 12 ] It has pronounced sexual dimorphism , more so than any other bat species in the world, [ 12 ] with males up to twice as heavy as females.
Bipalium species are predatory.Some species prey on earthworms, while others may also feed on mollusks. [10] [11] These flatworms can track their prey.

Bats have been traditionally thought to be a monophyletic group; according to this model, all living fruit bats and microbats (Microchiroptera) are descendants of a common ancestor species that was already capable of flight. [3] However, there are alternate hypotheses which conclude that bats are polyphyletic.
Polyctenidae species or bat bugs are obligate, hematophagous ectoparasites of bats. These insects are not to be confused with cimicid bat bugs , which are members of the family Cimicidae . A significant relationship appears to occur between the family groups and the species of hosts that indicates co-evolution and specialization. [ 1 ]
