Mouse-tailed bats are a group of insectivorous microbats of the family Rhinopomatidae with only three to six species, all contained in the single genus Rhinopoma. [2] They are found in the Old World, from North Africa to Thailand and Sumatra, in arid and semiarid regions, roosting in caves, houses and even the Egyptian pyramids. They are relatively small, with a body length of just 5 to 6 cm. [3] They weigh between 6 and 14 g.
Rhinopomatidae are small bats with very slim limbs and a long, thin, hairless tail, which is nearly the same length as the rest of the body and not connected to the patagium. Their sand-colored coat is soft and short. The snout has a small and simple nose leaf with valvular nostrils. Their big ears have a well-developed tragus and are connected to their big, black eyes by a band of skin across the forehead. [4] There is a fat repository located near the caudal penduncle and the hind legs. Of all the bats, Rhinopomatidae have the shortest fingers relative to their forearm-length. They have a head-body length of 50 to 90 mm, forearm-length of 45 to 75 mm, a tail-length of 40 to 80 mm and a body weight of 6 to 14 grams.
Rhinopomatidae live in deserts and semi-arid climates in North Africa and South Asia, from Morocco and Senegal to South Sudan, the Middle East and India to Myanmar, Thailand, and North-Sumatra. They also come to agricultural areas and disturbed areas. They are adaptable and live along walls with low humidity and high temperatures. They also use crevices, rock walls, houses, tombs (including the Egyptian Pyramids, where they have been coming for more than three-thousand years), tunnels and caves as shelters. Animals from the more northern parts of South-Asia travel to winter colonies, where they become torpid, although they do not truly hibernate. In very dry periods during a food shortage they estivate, where they live on their fat stores.
Rhinopomatidae live in colonies of thousands, where they gather in small, scattered groups. Mixed groups are common but groups with only males or females also occur. They live in roosts of a thousand or more members, and have one or two young per year. [4] They have poor flight endurance and fast fliers quickly become exhausted. They can also quickly run on the ground. They hunt small insects including beetles that have flight altitudes of five to ten meters.
This family is closely related to Kitti's hog-nosed bat, complementing the Rhinopomatidae in the superfamily Rhinopomatoidea. They are also closely related to horseshoe bats, Old World leaf-nosed bats and Plecotus , the other members of the suborder Yinpterochiroptera. There are four species that appear in the drier areas of North Africa and in southern Asia. There are no known fossils.
Family Rhinopomatidae
The inland broad-nosed bat is a species of vesper bat. They are endemic to Australia and widespread throughout the inland, especially in arid and semi-arid regions. This insectivorous microbat, measuring 12 centimetres (4.7 in) in length, roosts in tree hollows during the day and forages over woodland and water at night.
The silver-haired bat is a solitary migratory species of vesper bat in the family Vespertilionidae and the only member of the genus Lasionycteris.
The inland forest bat is a vesper bat that occurs in central and arid regions in Australia. They were first described in 1987, published in a review of poorly surveyed microbat populations. A tiny flying mammal, it occupies small cavities in trees and buildings while roosting. The nocturnal activity is foraging for insects, typically moths.
The lesser mouse-tailed bat is a species of microbat in the family Rhinopomatidae. Also referred to as Hardwicke's lesser mouse-tailed bat and long-tailed bat, it is named after Major General Thomas Hardwicke (1755–1835), an English soldier and naturalist who served many years in India. It is found in North Africa, some parts of central and eastern Africa, West Asia and east to the Indian subcontinent.
The greater mouse-tailed bat is a species of bat in the Rhinopomatidae family.
The small mouse-tailed bat is a species of bat in the Rhinopomatidae family. It is found in Afghanistan, Iran, Oman, and possibly Ethiopia, ranging from the Sistan Basin in Iran well into the Helmand River basin of south-western Afghanistan.
The little brown bat or little brown myotis is an endangered species of mouse-eared microbat found in North America. It has a small body size and glossy brown fur. It is similar in appearance to several other mouse-eared bats, including the Indiana bat, northern long-eared bat, and Arizona myotis, to which it is closely related. Despite its name, the little brown bat is not closely related to the big brown bat, which belongs to a different genus.
The lesser short-nosed fruit bat is a species of megabat within the family Pteropodidae. It is a small bat that lives in South Asia and Southeast Asia. It weighs between 21 and 32 grams, and measures 70 to 127 millimetres. It occurs in many types of habitat, but most frequently in disturbed forest, including lower montane forest and tropical lowland rain forest, plus gardens, mangroves, and vegetation on beaches.
The Yemeni mouse-tailed bat is an endangered species of bat found in Yemen. It is only known from one roost, and its population is estimated at 150 individuals.
The Egyptian mouse-tailed bat is a species of mouse-tailed bat found in North Africa and the Middle East.
