Molossus Ater
The black mastiff bat (''Molossus rufus'') is a bat species. It ranges from the northern region of South America (excluding Chile), most of Central America (excluding Belize) and parts of southern Mexico. Taxonomy The black mastiff bat was described as a new species in 1805 by French naturalist Étienne Geoffroy Saint-Hilaire. The holotype had been collected in Cayenne, French Guiana. Description Males have a forearm length ranging from and females' forearm lengths are . The fur of its back is usually shorter than . Individuals weight . It has a dental formula of for a total of 26 teeth. Range and habitat The black mastiff bat is a widespread species, occurring throughout much of Central and South America. Its range includes the following countries: Argentina, Belize, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, El Salvador, French Guiana, Guatemala, Guyana, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Trinidad and Tobago, and Uruguay.

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 Louis-Jean-Marie Daubenton at the College de France and Fourcroy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bats Of Mexico
Bats are flying mammals of the Order (biology), order Chiroptera (). With their forelimbs adapted as Bat wing development, wings, they are the only mammals capable of true and sustained Bat flight, 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 organisms, 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 Animal echolocation, echolocating microbats. But more recent evidence has supported dividing the or ...

Mammals Described In 1805
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...

Mammals Of Argentina
This is a list of the native mammal species recorded in Argentina. As of January 2020, the list contains 402 mammal species from Argentina, of which one is extinct, seven are critically endangered, seventeen are endangered, sixteen are vulnerable, and thirty are near threatened. The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature; those on the left are used here, those in the second column in some other articles: Subclass: Theria Infraclass: Metatheria Superorder: Ameridelphia =Order: Didelphimorphia (common opossums)= Didelphimorphia is the order of common opossums of the Western Hemisphere. Opossums probably diverged from the basic South American marsupials in the late Cretaceous or early Paleocene. They are small to medium-sized marsupials, about the size of a large house cat, with a long snout and prehensile tail. *Family: Didelphidae (American opossums) **Subfamily: Caluromyi ...

A mammal () is a vertebrate animal of the class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three middle ear bones.

Molossus (bat)
''Molossus'' is a genus of Chiroptera, bats. The genus contains ten species with a New World distribution from Mexico in the north to northern Argentina at its most southerly limit. Four of these species have distributions that include various islands in the West Indies such as Puerto Rico or Trinidad. The genus belongs to a group commonly referred to as free-tailed bats. Its name is from the ancient Molossus (dog), Molossus breed of shepherd dog.''The Mammals of the Southern African Sub-region'' by J. D. Skinner, , 2006, p. 277, "The name of the [free-tailed bats] family is derived from the Greek ''molossus'', a kind of dog used by Greek shepherds in ancient times." __TOC__ Systematics The following species are recognised: * ''Molossus alvarezi'' * ''Molossus aztecus'' Saussure, 1860 * ''Bonda mastiff bat, Molossus bondae'' * ''Molossus coibensis'' Allen, 1904 * ''Molossus currentium'' Thomas, 1901 * ''Molossus molossus'' (Pallas, 1766) * ''Molossus pretiosus'' Miller, 1902 * '' ...
