Snake
Snakes are elongated, Limbless vertebrate, limbless, carnivore, carnivorous reptiles of the suborder Serpentes . Like all other Squamata, squamates, snakes are ectothermic, amniote vertebrates covered in overlapping Scale (zoology), scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads (cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, altho ...

Trinidad And Tobago
Trinidad and Tobago (, ), officially the Republic of Trinidad and Tobago, is the southernmost island country in the Caribbean. Consisting of the main islands Trinidad and Tobago, and numerous much smaller islands, it is situated south of Grenada and off the coast of northeastern Venezuela. It shares maritime boundaries with Barbados to the northeast, Grenada to the northwest and Venezuela to the south and west. Trinidad and Tobago is generally considered to be part of the West Indies. The island country's capital is Port of Spain, while its largest and most populous city is San Fernando. The island of Trinidad was inhabited for centuries by Indigenous peoples before becoming a colony in the Spanish Empire, following the arrival of Christopher Columbus, in 1498. Spanish governor José María Chacón surrendered the island to a British fleet under the command of Sir Ralph Abercromby in 1797. Trinidad and Tobago were ceded to Britain in 1802 under the Treaty of Amiens as se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venezuela
Venezuela (; ), officially the Bolivarian Republic of Venezuela ( es, link=no, República Bolivariana de Venezuela), is a country on the northern coast of South America, consisting of a continental landmass and many islands and islets in the Caribbean Sea. It has a territorial extension of , and its population was estimated at 29 million in 2022. The capital and largest urban agglomeration is the city of Caracas. The continental territory is bordered on the north by the Caribbean Sea and the Atlantic Ocean, on the west by Colombia, Brazil on the south, Trinidad and Tobago to the north-east and on the east by Guyana. The Venezuelan government maintains a claim against Guyana to Guayana Esequiba. Venezuela is a federal presidential republic consisting of 23 states, the Capital District and federal dependencies covering Venezuela's offshore islands. Venezuela is among the most urbanized countries in Latin America; the vast majority of Venezuelans live in the cities of the n ...

Mastigodryas
''Mastigodryas'' is a genus of colubrid snakes. Like some other colubrids, they are commonly called racers. It is a Neotropical genus, with members distributed from Mexico to Argentina and several islands in the Caribbean. Some authorities use the older generic name, ''Dryadophis'', for these species. Savage JM (2002). ''The Amphibians and Reptiles of Costa Rica: A Herpetofauna Between Two Continents, Between Two Seas''. Chicago: University of Chicago Press. p. 673. Description These snakes are cylindrical or somewhat laterally compressed in shape. The head is distinct from the rest of the body, as in many other colubrids. They have large eyes. They have Duvernoy's glands. The morphology of the hemipenis in various species has been helpful in elucidating their relationships, as little is known about the evolutionary origins of the genus.

Reptiles Described In 1938
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates ( lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated ...
