Fauna Of Trinidad And Tobago
Trinidad and Tobago are continental islands with a geologically very recent history of direct land bridge connection to South America. As a result, unlike most of the Caribbean Islands, Trinidad and Tobago supports a primarily South American flora and fauna and has greater diversity of plant and animal species than the Antilles. However, rates of endemism are lower than in the rest of the Caribbean because there has been less time for genetic isolation from mainland populations because of the history of land bridge connections and hence fewer opportunities for speciation, and so a greater proportion of the species in Trinidad and Tobago are also found on the South American mainland. Trinidad is nearer to mainland South America and has been directly connected to the mainland via land bridges more often and for longer periods than Tobago. This, as well as Trinidad's larger size and more varied topography and hydrology compared to that of Tobago allow greater species and ecosystem ...

Carnivora
Carnivora is a Clade, monophyletic order of Placentalia, placental mammals consisting of the most recent common ancestor of all felidae, cat-like and canidae, dog-like animals, and all descendants of that ancestor. Members of this group are formally referred to as carnivorans, and have evolved to specialize in eating flesh. The order is the fifth largest order of mammals, comprising at least 279 species. Carnivorans live on every major landmass and in a variety of habitats, ranging from the cold polar regions to the hyper-arid region of the Sahara Desert to the open seas. They come in a very large array of different body plans in contrasting shapes and sizes. Carnivora can be divided into two subclades: the cat-like Feliformia and the dog-like Caniformia, which are differentiated based on the structure of their ear bones and cranial features. The feliforms include families such as the felidae, cats, the hyenas, the mongooses and the viverridae, civets. The majority of felifor ...

Trinidad And Tobago Hummingbirds Composite
Trinidad is the larger and more populous of the two major islands of Trinidad and Tobago. The island lies off the northeastern coast of Venezuela and sits on the continental shelf of South America. It is often referred to as the southernmost island in the West Indies. With an area of , it is also the fifth largest in the West Indies. Name The original name for the island in the Arawaks' language was which meant "Land of the Hummingbird". Christopher Columbus renamed it ('The Island of the Trinity'), fulfilling a vow he had made before setting out on his third voyage. This has since been shortened to ''Trinidad''. History Caribs and Arawaks lived in Trinidad long before Christopher Columbus encountered the islands on his third voyage on 31 July 1498. The island remained Spanish until 1797, but it was largely settled by French colonists from the French Caribbean, especially Martinique.Besson, Gerard (2000-08-27).

Manatee
Manatees (family Trichechidae, genus ''Trichechus'') are large, fully aquatic, mostly herbivorous marine mammals sometimes known as sea cows. There are three accepted living species of Trichechidae, representing three of the four living species in the order Sirenia: the Amazonian manatee (''Trichechus inunguis''), the West Indian manatee (''Trichechus manatus''), and the West African manatee (''Trichechus senegalensis''). They measure up to long, weigh as much as , and have paddle-like tails. Manatees are herbivores and eat over 60 different freshwater and saltwater plants. Manatees inhabit the shallow, marshy coastal areas and rivers of the Caribbean Sea, the Gulf of Mexico, the Amazon basin, and West Africa. The main causes of death for manatees are human-related issues, such as habitat destruction and human objects. Their slow-moving, curious nature has led to violent collisions with propeller-driven boats and ships. Some manatees have been found with over 50 scars on them ...

Tufted Capuchin
The tufted capuchin (''Sapajus apella''), also known as brown capuchin, black-capped capuchin, or pin monkey is a New World primate from South America and the Caribbean islands of Trinidad and Margarita. As traditionally defined, it is one of the most widespread primates in the Neotropics, but it has recently been recommended considering the black-striped, black and golden-bellied capuchins as separate species in a new genus, thereby effectively limiting the tufted capuchin to the Amazon basin and nearby regions. However, the large-headed capuchin (''S. a. macrocephalus''), previously defined as a distinct species, has been reclassified as a subspecies of the tufted capuchin, expanding its range east to Peru & Ecuador and south to Bolivia. The tufted capuchin is an omnivorous animal, mostly feeding on fruits and invertebrates, although it sometimes feeds on small vertebrates (e.g. lizards and bird chicks) and other plant parts. It can be found in many different kinds of environm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humboldt's White-fronted Capuchin
Humboldt's white-fronted capuchin (''Cebus albifrons'') is a species of gracile capuchin monkey. It is found in Colombia, Venezuela, Brazil, and potentially the island of Trinidad. Taxonomy The species name ''Cebus albifrons'' was formerly considered to also include several types of white-fronted capuchin monkey which are now regarded as separate species based on genetic studies by Boubli and Lynch Alfaro. Trinidad white-fronted capuchin Boubli ''et al''. found in a 2012 study that the Trinidad white-fronted capuchin, capuchins on Trinidad, previously classified as ''C. albifrons trinitatis'', had derived from within ''C. olivaceus brunneus'' (or more specifically, the mitochondrial genes of the single Trinidad specimen they sampled derived from ''brunneus''). However, the morphological distinctiveness of Trinidad populations has led to doubts over this taxonomy. Further complicating this taxonomy is the fact that subsequent morphological inspection of the ''C. brunneus'' spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Collared Peccary
The collared peccary (''Dicotyles tajacu'') is a species of artiodactyl (even-toed) mammal in the family Tayassuidae found in North, Central, and South America. It is the only member of the genus ''Dicotyles''. They are commonly referred to as ''javelina, saíno'', or ''báquiro'', although these terms are also used to describe other species in the family. The species is also known as the musk hog. In Trinidad, it is colloquially known as ''quenk''. Taxonomy Although somewhat related to true Old World pigs, and frequently referred to as a pig, this species and the other peccaries are no longer classified in the pig family, Suidae. Although formerly classified in the genus ''Pecari'', studies in 2020 placed them in the genus ''Dicotyles'', based on an unequivocal type-species selection; these studies have been accepted by the American Society of Mammalogists. Currently, the IUCN still places them in the genus ''Pecari''. Description The collared peccary stands around tall at th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Brocket
The red brocket (''Mazama americana'') is a species of brocket deer from forests in South America, ranging from northern Argentina to Colombia and the Guianas. It also occurs on the Caribbean island of Trinidad (it also occurred on the island of Tobago until very recent historical times, but has been extirpated there). Taxonomy It formerly included the Central American red brocket (''M. temama'') and sometimes the Yucatan brown brocket (''M. pandora'') as subspecies. Considerable taxonomic confusion still exists for the populations remaining in the red brocket. Pending a solution to this, it has been evaluated as data deficient by the IUCN, though as presently defined, it is the most widespread species of brocket. It is sympatric with the smaller Amazonian brown brocket over much of its range (the latter tends to have significantly lower population densities).

Naturalisation (biology)
Naturalisation (or naturalization) is the ecological phenomenon through which a species, taxon, or population of exotic (as opposed to native) origin integrates into a given ecosystem, becoming capable of reproducing and growing in it, and proceeds to disseminate spontaneously. In some instances, the presence of a species in a given ecosystem is so ancient that it cannot be presupposed whether it is native or introduced. Generally, any introduced species may (in the wild) either go extinct or naturalise in its new environment. Some populations do not sustain themselves reproductively, but exist because of continued influx from elsewhere. Such a non-sustaining population, or the individuals within it, are said to be adventive. Cultivated plants are a major source of adventive populations. The above refers to ''naturalize'' as an intransitive verb, as in, "The species naturalized". In North America it is common to use ''naturalize'' as a transitive verb, as in, "City staff nat ...

Small Indian Mongoose
The small Indian mongoose (''Urva auropunctata'') is a mongoose species native to Iraq and northern South Asia; it has also been introduced to many regions of the world, such as several Caribbean and Pacific islands. Taxonomy ''Mangusta auropunctata'' was the scientific name proposed by Brian Houghton Hodgson in 1836 for a mongoose specimen collected in central Nepal. It was later classified in the genus ''Herpestes'', but all Asian mongooses are now thought to belong in the genus ''Urva''. In the 19th and 20th centuries, several zoological specimens were described: *''Mangusta pallipes'' proposed by Edward Blyth in 1845 were mongooses observed in Kandahar, Afghanistan. *''Herpestes palustris'' proposed by R. K. Ghose in 1965 was an adult male mongoose collected in a swamp on the eastern fringe of Kolkata, India. The small Indian mongoose was once considered a subspecies of the Javan mongoose (''H. javanicus''). Genetic analysis of hair and tissue samples from 18 small Indian an ...
