Northern Free-tailed Bat
The northern free-tailed bat (''Mops johorensis'') is a species of bat in the family Molossidae. It is found in Indonesia and Malaysia. Taxonomy and etymology It was described as a new species in 1873 by Irish zoologist George Edward Dobson. Dobson had obtained the holotype from James Wood-Mason. Dobson initially placed it in the genus '' Molossus'' and the subgenus ''Nyctinomus'', with a scientific name of ''Molossus (Nyctinomus) johorensis''. Its species name "''johorensis''" is Latin for "belonging to Johor." Johor is a state in Malaysia; the holotype was collected there. Description Its ears are large and round. Its tragi are small and squarish in shape. Its ears are connected to each other by a band of tissue called the interaural membrane. As a free-tailed bat, its tail extends beyond the uropatagium. Its dental formula is , for a total of 36 teeth. Conservation It is currently listed as vulnerable Vulnerable may refer to: General * Vulnerability * Vulnerability (co ...

George Edward Dobson
George Edward Dobson FRS FLS FZS (4 September 1848 at Edgeworthstown, County Longford, Ireland – 26 November 1895) was an Irish zoologist, photographer and army surgeon. He took a special interest in bats, describing many new species, and some species have been named after him. Biography Dobson was the eldest son of Parke Dobson Proceedings of the Royal Society. Volume 59. p 15. Royal Society. 1896 and was educated at the Royal School Enniskillen and then at Trinity College, Dublin. He gained the degrees of Bachelor of Arts in 1866, Bachelor of Medicine, Bachelor of Surgery and Master of Surgery in 1867 and Master of Arts in 1875. He became an army surgeon after 1867 serving in India and rose to the position of surgeon major. In 1868 he visited the Andaman Islands, collecting zoological specimens for the Indian Museum along with Wood-Mason, and in May 1872 he made ethnological and photographic studies of the Andamanese peoples. Around 1878, he became curator of the Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tragus (ear)
The tragus is a small pointed eminence of the external ear, situated in front of the concha, and projecting backward over the meatus. It also is the name of hair growing at the entrance of the ear. Its name comes the Ancient Greek (), meaning 'goat', and is descriptive of its general covering on its under surface with a tuft of hair, resembling a goat's beard. The nearby antitragus projects forwards and upwards. Because the tragus faces rearwards, it aids in collecting sounds from behind. These sounds are delayed more than sounds arriving from the front, assisting the brain to sense front vs. rear sound sources. In a positive fistula test (for the presence of a fistula from cholesteatoma to the labyrinth), pressure on the tragus causes vertigo or eye deviation by inducing movement of perilymph. Other animals The tragus is a key feature in many bat species. As a piece of skin in front of the ear canal, it plays an important role in directing sounds into the ear for prey loc ...

Taxonomy Articles Created By Polbot
Taxonomy is the practice and science of categorization or classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic units known as "taxa" (singular "taxon")." Taxonomy is different from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Described In 1873
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla ( hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora ( cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saur ...

Mops (bat)
''Mops'' (mastiff bats or free-tailed bats) is a genus of bats in the family Molossidae. Molecular sequence data indicates that ''Mops'' and '' Chaerephon'' are not monophyletic taxa. However, the grouping of ''Chaerephon'' and ''Mops'' was found to be monophyletic when excluding ''C. jobimena''. Species within this genus are:Simmons, 2005, pp. 441–444; Stanley, 2008 Genus ''Mops'' - greater mastiff bats *Subgenus ''Xiphonycteris'' **Spurrell's free-tailed bat, ''Mops spurrelli'' **Dwarf free-tailed bat, ''Mops nanulus'' **Peterson's free-tailed bat, ''Mops petersoni'' **Sierra Leone free-tailed bat, ''Mops brachypterus'' ** Bakari's free-tailed bat, ''Mops bakarii'' **Railer bat, ''Mops thersites'' *Subgenus ''Mops'' ** Angolan free-tailed bat, ''Mops condylurus'' **White-bellied free-tailed bat, ''Mops niveiventer'' **Mongalla free-tailed bat, ''Mops demonstrator'' **Malayan free-tailed bat, ''Mops mops'' **Sulawesi free-tailed bat, ''Mops sarasinorum'' **Trevor's free-taile ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulnerable Species
A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature as being threatened with extinction unless the circumstances that are threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A taxon is Vulnerable when it is not critically endangered or Endangered but ...

Dentition
Dentition pertains to the development of teeth and their arrangement in the mouth. In particular, it is the characteristic arrangement, kind, and number of teeth in a given species at a given age. That is, the number, type, and morpho-physiology (that is, the relationship between the shape and form of the tooth in question and its inferred function) of the teeth of an animal. Animals whose teeth are all of the same type, such as most non-mammalian vertebrates, are said to have '' homodont'' dentition, whereas those whose teeth differ morphologically are said to have ''heterodont'' dentition. The dentition of animals with two successions of teeth (deciduous, permanent) is referred to as ''diphyodont'', while the dentition of animals with only one set of teeth throughout life is ''monophyodont''. The dentition of animals in which the teeth are continuously discarded and replaced throughout life is termed ''polyphyodont''. The dentition of animals in which the teeth are set in soc ...

Interfemoral Membrane
The patagium (plural: patagia) is a membranous body part that assists an animal in obtaining lift when gliding or flight. The structure is found in extant and extinct groups of flying and gliding animals including bats, birds, some dromaeosaurs, pterosaurs, gliding mammals, some flying lizards, and flying frogs. The patagium that stretches between an animal's hind limbs is called the uropatagium (especially in bats) or the interfemoral membrane. Bats In bats, the skin forming the surface of the wing is an extension of the skin of the abdomen that runs to the tip of each digit, uniting the forelimb with the body. The patagium of a bat has four distinct parts: #Propatagium: the patagium present from the neck to the first digit. #Dactylopatagium: the portion found within the digits. #Plagiopatagium: the portion found between the last digit and the hindlimbs. #Uropatagium: the posterior portion of the flap between the two hindlimbs. Pterosaurs In the flying pterosaurs, the patagi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free-tailed Bat
The Molossidae, or free-tailed bats, are a family of bats within the order Chiroptera. The Molossidae is the fourth-largest family of bats, containing about 110 species as of 2012. They are generally quite robust, and consist of many strong-flying forms with relatively long and narrow wings with wrinkled lips shared through their genus. Their strong flying form allows them to fly 60 miles per hour using tail winds and at altitudes over 10,000 feet. This makes them unique among bats, as they are the only bat family that withstands the elevation. They are widespread, being found on every continent except Antarctica. They are typically found in caves, abandoned mines, or tunnels. Common ancestry The family's scientific name comes from the type genus '' Molossus'', which in turn is from the Molossus breed of dogs. The family's common name is derived from a length of "free" tail, projecting beyond the end of the uropatagium—the membrane that connects the base of the tail to the h ...
