Megabat long, thus smaller than some microbats, for example, the Mauritian tomb bat. The largest attain a wingspan of , and weigh as much as . Most fruit bats have large eyes, allowing them to orient themselves visually in twilight and inside caves and forests. Their sense of smell is excellent. In contrast to the microbats, the fruit bats do not use echolocation (with one exception, the Egyptian fruit bat "Rousettus egyptiacus", which uses high-pitched tongue clicks to navigate in caves). Megabats make up the only family (Pteropodidae) in order Chiroptera that is not capable of laryngeal echolocation. Echolocation and flight
Bahaman funnel-eared bat close to 50% of their mothers’ weight. Females are fully responsible for giving care to their newborn, due to the fact that they give one offspring per event. The population of the Bahaman funnel-eared bat is decreasing due to their declining habitat environment. All funnel-eared bats have, very large and funnel-shaped ears. These allow them to detect near silent sounds and return echoes through echolocation. Small papillae cover the ears of these bats, which increases auditory sensitivity. They use olfactory and tactile cues in communication as other mammals do. This species is not very well known, because they are only
