Manicou Fig
The common opossum (''Didelphis marsupialis''), also called the southern or black-eared opossum or gambá, and sometimes called a possum, is a marsupial species living from the northeast of Mexico to Bolivia (reaching the coast of the South Pacific Ocean to the central coast of Peru), including Trinidad and Tobago in the Caribbean, where it is called manicou. It prefers the woods, but can also live in fields and cities. Habitat and shelter This opossum is found in tropical and subtropical forest, both primary and secondary, at altitudes up to 2200 m. They use a wide range of nest sites. Most commonly they will create one in the hollow of a tree; however, they will also dig a burrow or nest in any dark location if nothing else is suitable (which often gets them in trouble with humans). Opossums enjoy denning underground, but do not spend as much time underground when it is dry season. Common predators of the opossum are humans, house pets (ex: dogs and cats), and birds. When ...

Caracas
Caracas (, ), officially Santiago de León de Caracas, abbreviated as CCS, is the capital and largest city of Venezuela, and the center of the Metropolitan Region of Caracas (or Greater Caracas). Caracas is located along the Guaire River in the northern part of the country, within the Caracas Valley of the Venezuelan coastal mountain range (Cordillera de la Costa). The valley is close to the Caribbean Sea, separated from the coast by a steep 2,200-meter-high (7,200 ft) mountain range, Cerro El Ávila; to the south there are more hills and mountains. The Metropolitan Region of Caracas has an estimated population of almost 5 million inhabitants. The center of the city is still ''Catedral'', located near Bolívar Square, though some consider the center to be Plaza Venezuela, located in the Los Caobos area. Businesses in the city include service companies, banks, and malls. Caracas has a largely service-based economy, apart from some industrial activity in its metropolitan ar ...

Gigantorhynchus Lutzi
''Gigantorhynchus'' is a genus of Acanthocephala (thorny-headed worms, also known as spiny-headed worms) that parasitize marsupials, anteaters, and possibly baboons by attaching themselves to the intestines using their hook-covered proboscis. Their life cycle includes an egg stage found in host feces, a cystacanth (larval) stage in an intermediate host such as termites, and an adult stage where cystacanths mature in the intestines of the host. This genus is characterized by a cylindrical proboscis with a crown of robust hooks at the apex followed by numerous small hooks on the rest of the proboscis, a long body with pseudosegmentation, filiform lemnisci, and ellipsoid testes. The largest known specimen is the female ''G. ortizi'' with a length of around and a width of . Genetic analysis on one species of ''Gigantorhynchus'' places it with the related genus ''Mediorhynchus'' in the family Gigantorhynchidae. Six species in this genus are distributed across Central and South A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of Trinidad And Tobago
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 Sauropsid ...

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 ...

Mammals Of The Caribbean
A unique and diverse albeit phylogenetically restricted mammal fauna is known from the Caribbean region. The region—specifically, all islands in the Caribbean Sea (except for small islets close to the continental mainland) and the Bahamas, Turks and Caicos Islands, and Barbados, which are not in the Caribbean Sea but biogeographically belong to the same Caribbean bioregion—has been home to several families found nowhere else, but much of this diversity is now extinct. The bat faunas of much of the Caribbean show similarities that led to the proposal of a distinct Caribbean faunal region, bounded by "Koopman's Line". This region excludes several of the region's islands, including the Grenadines, Grenada, Trinidad, Tobago, and other islands near the American mainland, such as Margarita, Isla Escudo de Veraguas, Rosario Islands, Cozumel, and the Florida Keys. The faunas of islands outside Koopman's Line are similar to those of the adjacent mainland, though usually smaller; in con ...

Marsupials Of South America
Marsupials are any members of the mammalian infraclass Marsupialia. All extant marsupials are endemic to Australasia, Wallacea and the Americas. A distinctive characteristic common to most of these species is that the young are carried in a pouch. Marsupials include opossums, Tasmanian devils, kangaroos, koalas, wombats, wallabies, bandicoots, and the extinct thylacine. Marsupials represent the clade originating from the last common ancestor of extant metatherians, the group containing all mammals more closely related to marsupials than to placentals. They give birth to relatively undeveloped young that often reside in a pouch located on their mothers' abdomen for a certain amount of time. Close to 70% of the 334 extant species occur on the Australian continent (the mainland, Tasmania, New Guinea and nearby islands). The remaining 30% are found in the Americas—primarily in South America, thirteen in Central America, and one species, the Virginia opossum, in North America, nor ...

Opossums
Opossums () are members of the marsupial order Didelphimorphia () endemic to the Americas. The largest order of marsupials in the Western Hemisphere, it comprises 93 species in 18 genera. Opossums originated in South America and entered North America in the Great American Interchange following the connection of North and South America. The Virginia opossum is the only species found in the United States and Canada. It is often simply referred to as an opossum, and in North America it is commonly referred to as a possum (; sometimes rendered as ''possum'' in written form to indicate the dropped "o"). Possums should not be confused with the Australasian arboreal marsupials of suborder Phalangeriformes that are also called possums because of their resemblance to the Didelphimorphia. The opossum is typically a nonaggressive animal. Etymology The word ''opossum'' is borrowed from the Powhatan language and was first recorded between 1607 and 1611 by John Smith (as ''opassom'') an ...

Lance-tailed Manakin
The lance-tailed manakin (''Chiroxiphia lanceolata'') is a small passerine bird which breeds in tropical Central and South America from Costa Rica to northern Venezuela. This manakin is a fairly common bird of dry and moist deciduous forests, but not rainforest. It is a small, compact bird about long and similar to the blue-backed manakin, but both sexes have the two central tail feathers elongated to form a spike. Males have black plumage with a blue back, a red crown and orange legs. Females and juveniles are olive-green with paler underparts. At breeding time, males are involved in a cooperative behaviour during which they jump up and down alternately. This is a fairly common species with a wide range, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern". Description Like other manakins, the lance-tailed manakin is a compact, brightly coloured forest bird, typically 13.5 cm long and weighing 17.5 g. ...

Crotalus Durissus
''Crotalus durissus'', known as the South American rattlesnake, tropical rattlesnake,Mehrtens JM. 1987. Living Snakes of the World in Color. New York: Sterling Publishers. 480 pp. and by other names, is a highly venomous pit viper species found in South America. It is the most widely distributed member of its genus. Currently, seven subspecies are recognized. Taxonomy The Guiana rattlesnake, previously recognized as ''C. d. dryinus'', is now considered a synonym for ''C. d. durissus''. In fact, after the previous nominate subspecies for the ''C. d. durissus'' complex became the current nominate for ''Crotalus simus'', which now represents its Mexican and Central American members, ''C. d. dryinus'' became the new nominate for the South American rattlesnakes as represented by ''C. durissus''. The subspecies previously known as ''C. d. collilineatus'' and ''C. d. cascavella'' were moved to the synonymy of ''C. d. terrificus'' following the publication of a paper by Wüster ''et a ...

Cane Toad
The cane toad (''Rhinella marina''), also known as the giant neotropical toad or marine toad, is a large, terrestrial true toad native to South and mainland Central America, but which has been introduced to various islands throughout Oceania and the Caribbean, as well as Northern Australia. It is a member of the genus ''Rhinella'', which includes many true toad species found throughout Central and South America, but it was formerly assigned to the genus ''Bufo''. The cane toad is an old species. A fossil toad (specimen UCMP 41159) from the La Venta fauna of the late Miocene in Colombia is indistinguishable from modern cane toads from northern South America. It was discovered in a floodplain deposit, which suggests the ''R. marina'' habitat preferences have long been for open areas. The cane toad is a prolific breeder; females lay single-clump spawns with thousands of eggs. Its reproductive success is partly because of opportunistic feeding: it has a diet, unusual among anuran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
