Black Mastiff Bat
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 Daubenton at the College de France and Fourcroy at the Jardin des Pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of Mexico
This is a list of the native wild mammal species recorded in Mexico. As of September 2014, there were 536 mammalian species or subspecies listed. Based on International Union for Conservation of Nature, IUCN data, Mexico has 23% more noncetacean mammal species than the U.S. and Canada combined in an area only 10% as large, or a species density over 12 times that of its northern neighbors. Mexico's high mammal biodiversity is in part a reflection of the wide array of biomes present over its latitudinal, climatic and altitudinal ranges, from lowland tropical rainforest to temperate desert to montane forest to alpine tundra. The general increase in terrestrial biodiversity moving towards the equator is another important factor in the comparison. Mexico includes much of the Mesoamerica#Biodiversity, Mesoamerican and Madrean pine-oak woodlands biodiversity hotspots. From a biogeographic standpoint, most of Mexico is linked to the rest of North America as part of the Nearctic realm. Howeve ...

Bats Of Central America
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] |
Mammals Described In 1805
Mammals () are a group of vertebrate animals constituting the class (biology), class Mammalia (), characterized by the presence of mammary glands which in Female#Mammalian female, females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three ossicles, middle ear bones.

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: Ca ...

Molossus (bat)
''Molossus'' is a genus of 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 breed of shepherd dog.''The Mammals of the Southern African Sub-region'' by J. D. Skinner, , 2006, p. 277, "The name of the ree-tailed batsfamily is derived from the Greek ''molossus'', a kind of dog used by Greek shepherds in ancient times." Systematics The following species are recognised: * '' Molossus alvarezi'' * '' Molossus aztecus'' Saussure, 1860 *'' Molossus barnesi'' * '' Molossus coibensis'' Allen, 1904 * '' Molossus currentium'' Thomas, 1901 * ''Molossus molossus The velvety free-tailed bat or Pallas's mastiff bat (''Molossus molossus''), is a bat species in the famil ...
