List Of Snakes Of Trinidad And Tobago
Forty-seven species of snake have been recorded in Trinidad and Tobago, making the snake population of this area the most diverse in the Caribbean. Forty-four of these snake species are found in Trinidad and twenty-one in Tobago. Many of these species are South American, most of which are present in Venezuela. Trinidad and Tobago consists of two main islands, Trinidad and Tobago, and several smaller islands. The Islands of Trinidad and Tobago#Bocas Islands, Bocas Islands, which lie between Trinidad and Venezuela, in the Bocas del Dragón (''Dragon's Mouths''), consist of Chacachacare, Monos, Huevos (island), Huevos and Gaspar Grande. Several smaller islands lie off Trinidad, but snakes have been recorded on only one of them, Caledonia Island. Snakes have been recorded on one island off Tobago, Little Tobago. Four species are venom (poison), venomous: two coral snake species (''Micrurus'' spp.The abbreviation "sp." indicates a single species and the abbreviation "spp." indicat ...

Coral Snake
Coral snakes are a large group of elapid snakes that can be divided into two distinct groups, the Old World coral snakes and New World coral snakes. There are 16 species of Old World coral snakes, in three genera (''Calliophis'', '' Hemibungarus'', and ''Sinomicrurus''), and over 65 recognized species of New World coral snakes, in two genera (''Micruroides'' and ''Micrurus''). Genetic studies have found that the most basal lineages have origins in Asia, suggesting that the group originated in the Old World. While new world species of both genera are venomous, their bites are seldom lethal; only two confirmed fatalities have been documented in the past 100 years from the genus ''Micrurus''. Meanwhile, snakes of the genus ''Micruroides'' have never caused a medically-significant bite. North American coloration patterns Experts now recognize that certain coloration patterns and common mnemonics - such as the phrase “Red touch yellow, kill a fellow; red touch black, you’re good, ...

Typhlopidae
The Typhlopidae are a family of blind snakes. They are found mostly in the tropical regions of Africa, Asia, the Americas, and all mainland Australia and various islands. The rostral scale overhangs the mouth to form a shovel-like burrowing structure. They live underground in burrows, and since they have no use for vision, their eyes are mostly vestigial. They have light-detecting black eye spots, and teeth occur in the upper jaw. Typhlopids do not have dislocatable lower jaw articulations restricting them to prey smaller than their oral aperture. The tail ends with a horn-like scale. Most of these species are oviparous. Currently, 18 genera are recognized containing over 200 species. Geographic range They are found in most tropical and many subtropical regions all over the world, particularly in Africa, Asia, islands in the Pacific, tropical America, and southeastern Europe.

Epictia Tenella
''Epictia tenella'', also known as the Guyana blind snake, is a species of blind snake found on Trinidad in the Caribbean, and in South America, where it ranges from Guyana south to Brazil and northwestern Peru. It can reach a length of 170 mm (6-11/16 in) snout-to-vent. It has a medium brown dorsal surface, with a paler ventral surface and a yellow tail. Its head is dark except for a white to yellow spot covering the upper half of its rostral scale. It is mesophilic A mesophile is an organism that grows best in moderate temperature, neither too hot nor too cold, with an optimum growth range from . The optimum growth temperature for these organisms is 37°C. The term is mainly applied to microorganisms. Organi .... It burrows in damp soil and rotting vegetation, and possibly in ant and termite colonies. It feeds on ants, termites, millipedes, and eggs.

Fossorial
A fossorial () animal is one adapted to digging which lives primarily, but not solely, underground. Some examples are badgers, naked mole-rats, clams, meerkats, and mole salamanders, as well as many beetles, wasps, and bees. Prehistoric evidence The physical adaptation of fossoriality is widely accepted as being widespread among many prehistoric phyla and taxa, such as bacteria and early eukaryotes. Furthermore, fossoriality has evolved independently multiple times, even within a single family. Fossorial animals appeared simultaneously with the colonization of land by arthropods in the late Ordovician period (over 440 million years ago). Other notable early burrowers include ''Eocaecilia'' and possibly ''Dinilysia''. The oldest example of burrowing in synapsids, the lineage which includes modern mammals and their ancestors, is a cynodont, ''Thrinaxodon liorhinus'', found in the Karoo of South Africa, estimated to be 251 million years old. Evidence shows that this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Leptotyphlopidae
The Leptotyphlopidae (commonly called slender blind snakes or thread snakes) are a family of snakes found in North America, South America, Africa and Asia. All are fossorial and adapted to burrowing, feeding on ants and termites. Two subfamilies are recognized. Description Relatively small snakes, leptotyphlopids rarely exceed in length; only ''Trilepida macrolepis'' and ''Leptotyphlops occidentalis'' grow larger. The cranium and upper jaws are immobile and no teeth are in the upper jaw. The lower jaw consists of a much elongated quadrate bone, a tiny compound bone, and a relatively larger dentary bone. The body is cylindrical with a blunt head and a short tail. The scales are highly polished. The pheromones they produce protect them from attack by termites.''Field Guide to Snakes of Southern Africa'' - Bill Branch (Struik 1988) Among these snakes is what is believed to be the world's smallest: '' L. carlae'' ( Hedges, 2008).
