Megadermatidae
Megadermatidae, or false vampire bats, are a family of bats found from central Africa, eastwards through southern Asia, and into Australia. They are relatively large bats, ranging from 6.5 cm to 14 cm in head-body length. They have large eyes, very large ears and a prominent nose-leaf. They have a wide membrane between the hind legs, or uropatagium, but no tail. Many species are a drab brown in color, but some are white, bluish-grey or even olive-green, helping to camouflage them against their preferred roosting environments. They are primarily insectivorous, but will also eat a wide range of small vertebrates. Description False vampire bats are relatively large, with combined head and body lengths that range from . Their forearm lengths range from . They all lack tails. The ghost bat is the largest member of the family. All the species have very large ears with divided tragi. They have long nose-leaves.

Ghost Bat
The ghost bat (''Macroderma gigas'') is a species of bat found in northern Australia. The species is the only Australian bat that preys on large vertebrates – birds, reptiles and other mammals – which they detect using acute sight and hearing, combined with echolocation, while waiting in ambush at a perch. The wing membrane and bare skin is pale in colour, their fur is light or dark grey over the back and paler at the front. The species has a prominent and simple nose-leaf, their large ears are elongated and joined at lower half, and the eyes are also large and dark in colour. The first description of the species was published in 1880, its recorded range has significantly contracted since that time. Taxonomy A species of '' Macroderma'', one of several genera in the family Megadermatidae (false vampires). The family all have large eyes, a nose-leaf and tragus, long ears joined at the base, and are also found in southern Asia and central Africa. The description was published ...

Bat Genera
Bats are mammals of the order Chiroptera.''cheir'', "hand" and πτερόν''pteron'', "wing". With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more agile in flight than most birds, flying with their very long spread-out digits covered with a thin membrane or patagium. The smallest bat, and arguably the smallest extant mammal, is Kitti's hog-nosed bat, which is in length, across the wings and in mass. The largest bats are the flying foxes, with the giant golden-crowned flying fox, ''Acerodon jubatus'', reaching a weight of and having a wingspan of . The second largest order of mammals after rodents, bats comprise about 20% of all classified mammal species worldwide, with over 1,400 species. These were traditionally divided into two suborders: the largely fruit-eating megabats, and the echolocating microbats. But more recent evidence has supported dividing the order into Yinpterochiroptera and Yangochiropter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macroderma (bat)
''Macroderma'' is a genus of microbats, present in the fossil record and as one extant species. They have existed in Australia since the early Miocene. Taxonomy The description to the genus was published in a revision of chiropterans by Gerrit Smith Miller Jr. in 1906, separating the type species from it placement in the genus ''Megaderma''. The taxonomic placement is to family Megadermatidae of the suborder Microchiroptera. The name ''Macroderma'' combines the Greek words ''macros'' (large) and ''derma'' (skin), due to the large size of their partially conjoined ears. * ''Macroderma gigas'' Dobson, 1880 the only living species, a large predatory carnivore referred to as the Australian false vampyre or ghost bat * ''Macroderma godthelpi'', a fossil taxon describing the earliest and smallest species * '' Macroderma koppa'' Hand, Dawson & Augee, 1988. a fossil species that existed in the Pliocene epoch. * '' Macroderma malugara'' S.

Étienne Geoffroy Saint-Hilaire
Étienne Geoffroy Saint-Hilaire (15 April 177219 June 1844) was a French naturalist who established the principle of "unity of composition". He was a colleague of Jean-Baptiste Lamarck and expanded and defended Lamarck's evolutionary theories. Geoffroy's scientific views had a transcendental flavor (unlike Lamarck's materialistic views) and were similar to those of German morphologists like Lorenz Oken. He believed in the underlying unity of organismal design, and the possibility of the transmutation of species in time, amassing evidence for his claims through research in comparative anatomy, paleontology, and embryology. He is considered as a predecessor of the evo-devo evolutionary concept. Life and early career Geoffroy was born at Étampes (in present-day Essonne), and studied at the Collège de Navarre, in Paris, where he studied natural philosophy under M. J. Brisson. He then attended the lectures of Daubenton at the College de France and Fourcroy at the Jardin des Pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malayan Peninsula
The Malay Peninsula (Malay: ''Semenanjung Tanah Melayu'') is a peninsula in Mainland Southeast Asia. The landmass runs approximately north–south, and at its terminus, it is the southernmost point of the Asian continental mainland. The area contains Peninsular Malaysia, Southern Thailand, and the southernmost tip of Myanmar (Kawthaung). The island country of Singapore also has historical and cultural ties with the region.
