The Atrato slider (Trachemys medemi) is a species of turtle in the family Emydidae endemic to northwestern Colombia. [1] It was described in 2017. [1] [2]
The Atrato slider's geographical range is in the lower Atrato river basin of Antioquia and Chocó departments of northwestern Colombia, near the Panamanian border.
There were two major migrations of sliders into South America during the Great American Interchange of the Cenozoic. During the first migration, which occurred about 7.1-8.6 million years ago, the last recent common ancestor of T. medemi and T. dorbigni spread from Central America into South America, with T. dorbigni expanding into the eastern parts of the continent while T. medemi remained in present-day Colombia. T. medemi diverged from T. dorbigni about 2.8-4.1 million years ago, with T. dorbigni diversifying about 1.9-2.3 million years ago. In the meantime, during the second migration of Trachemys sliders 2.2-2.5 million years ago, T. venusta arrived in South America. [1]
The red-eared slider, also known as the red-eared terrapin, red-eared slider turtle, red-eared turtle, slider turtle, and water slider turtle, is a semiaquatic turtle belonging to the family Emydidae. It is a subspecies of the pond slider. It is the most popular pet turtle in the United States and is also popular as a pet across the rest of the world, and is the most invasive turtle. Because of this, it is the most commonly traded species of turtle in the world.
Trachemys is a genus of turtles belonging to the family Emydidae. The genus Trachemys is native to the Americas, ranging from the United States to northern Argentina.
The Atrato River is a river of northwestern Colombia. It rises in the slopes of the Western Cordillera and flows almost due north to the Gulf of Urabá, where it forms a large, swampy delta. Its course crosses the Chocó Department, forming that department's border with neighboring Antioquia in two places. Its total length is about 650 km (400 mi), and it is navigable as far as Quibdó, the capital of the department.
The Caribbean Plate is a mostly oceanic tectonic plate underlying Central America and the Caribbean Sea off the north coast of South America.
The Arrau turtle, also known as the South American river turtle, giant South American turtle, giant Amazon River turtle, Arrau sideneck turtle or simply the Arrau, is the largest of the side-neck turtles (Pleurodira) and the largest freshwater turtle in Latin America. The species primarily feeds on plant material and typically nests in large groups on beaches. Due to hunting of adults, collecting of their eggs, pollution, habitat loss, and dams, the Arrau turtle is seriously threatened.
The pond slider is a species of common, medium-sized, semiaquatic turtle. Three subspecies are described, the most recognizable of which is the red-eared slider, which is popular in the pet trade and has been introduced to other parts of the world by people releasing it to the wild. Hatchling and juvenile pond sliders have a greenish upper shell (carapace), yellow bottom shell (plastron), and green and yellow stripes and markings on their skin. These patterns and colors in the skin and shell fade with age until the carapace is a muted olive green to orange brown or brown and the plastron is a dull yellow or darker. Some sliders become almost black with few visible markings. The carapace is oval with a bit of rounding and a central crest with knobs, but these features soften and fade with age, adults being smoother and flatter. For determining an adult slider's sex, males typically have much longer front claws than adult females, while females usually have shorter, more slender tails than males. Their lifespans range from 20–50 years.
The Big Bend slider, also called the Mexican Plateau slider, is a species of aquatic turtle in the family Emydidae. The species is endemic to the Southwestern United States and northern Mexico.
The Cumberland slider, also called commonly the Cumberland turtle and Troost's turtle, is a subspecies of semiaquatic turtle (terrapin) in the family Emydidae. The subspecies is indigenous to the Southeastern United States.
The Magdalena River turtle, or Rio Magdalena river turtle, is a species of turtle in the family Podocnemididae, which diverged from other turtles in the Cretaceous Period, 100 million years ago. It is endemic to northern Colombia, where its home range consists of the Sinú, San Jorge, Cauca, and Magdalena river basins.
The Central Antillean slider, is a species of turtle in the family Emydidae. The species is found on three islands in the West Indies: Hispaniola, Great Inagua, and Puerto Rico.
The Jamaican slider also known as the Cat Island slider is a species of fresh water turtle in the family Emydidae. It is found in the Bahamas and Jamaica. As it is not currently found on any of the other surrounding islands in the region it is assumed that the Jamaican slider was introduced from one of these countries to the other. Even though the popular theory was that these turtles originated from Jamaica, current geological evidence may suggest that they were in the Bahamas long before the native Indians first went to the Bahama islands. There is also evidence from archeological sites on San Salvador that the native Indians ate these turtles and transplanted them around the West Indies.
The yellow-bellied slider is a land and water turtle belonging to the family Emydidae. This subspecies of pond slider is native to the southeastern United States, specifically from Florida to southeastern Virginia, and is the most common turtle species in its range. It is found in a wide variety of habitats, including slow-moving rivers, floodplain swamps, marshes, seasonal wetlands, and permanent ponds. Yellow-Bellied Sliders are popular as pets.
Titanoboa is an extinct genus of very large snakes that lived in what is now La Guajira in northeastern Colombia. They could grow up to 12.8 m (42 ft) long and reach a weight of 1,135 kg (2,500 lb).
D'Orbigny's slider or the black-bellied slider, commonly known in Brazil as tartaruga-tigre or tartaruga-tigre-d'água, is a species of water turtle in the family Emydidae. The species is found in southern Brazil, northeastern Argentina, and Uruguay. Two subspecies are recognized as being valid, Trachemys dorbigni adiutrix and Trachemys dorbigni brasiliensis.
Turtle farming is the practice of raising turtles and tortoises of various species commercially. Raised animals are sold for use as gourmet food, traditional medicine ingredients, or as pets. Some farms also sell young animals to other farms, either as breeding stock, or more commonly to be raised there to a larger size for subsequent resale.
