The Phyllostomidae, also known as New World leaf-nosed bats, are among the most ecologically diverse mammal families. [6] This variation is measured by diversity in skull morphology and diet-related characteristics: Phyllostomidae consists of species that have evolved physical modifications for insectivory, frugivory, hematophagy, nectarivory, and omnivory.
They range in size from the Malayan tailless leaf-nosed bat, at 3 cm (1 in) and no tail, to the striped leaf-nosed bat, at 13 cm (5 in) plus a 4 cm (2 in) tail. Like all bats, hipposiderids are capable of true and sustained flight , and have wing lengths ranging from multiple species with 3 cm (1 in), to the giant roundleaf bat at 13 cm (5 in).
Kitti's hog-nosed bat is small at about 29 to 33 mm (1.1 to 1.3 in) in length and 2 g (0.071 oz) in mass, [2] [3] hence the common name of "bumblebee bat". It is the smallest species of bat and may be the world's smallest mammal, depending on how size is defined.
A heterodyne bat detector does not give a very accurate measurement of the frequency of a bat call, One reason is that the call frequencies can easily vary by 1 kHz or more due to the doppler shift. To track these changes and to get a more precise frequency, a frequency division bat detector or a time expansion bat detector is used using a ...
Vespertilionidae is a family of microbats, of the order Chiroptera, flying, insect-eating mammals variously described as the common, vesper, or simple nosed bats. The vespertilionid family is the most diverse and widely distributed of bat families, specialised in many forms to occupy a range of habitats and ecological circumstances, and it is ...
Sundevall's roundleaf bat (Hipposideros caffer), also called Sundevall's leaf-nosed bat, [2] is a species of bat in the family Hipposideridae. These bats are very similar in appearance to the closely related Noack's roundleaf bat , and the two have in the past been considered to be the same species.
Nose-leaf diagram of a horseshoe bat. A nose-leaf, or leaf nose, is an often large, lance-shaped nose, found in bats of the Phyllostomidae, Hipposideridae, and Rhinolophidae families. Because these bats echolocate nasally, this nose-leaf is thought to serve a role in modifying and directing the echolocation call. [1] [2]
The trident bat or trident leaf-nosed bat (Asellia tridens) is a species of bat in the family Hipposideridae. It is widely distributed in the Middle East, South and Central Asia, and North, East, and Central Africa. Its natural habitats are subtropical or tropical dry forests, dry savanna, subtropical or tropical dry shrubland, caves and hot ...
