Texas River Cooter
The Texas river cooter (''Pseudemys texana'') is a species of freshwater turtle endemic to the U.S. state of Texas. It is found in the river basins of the Brazos, San Bernard, Colorado, Guadalupe, San Antonio, Nueces, and their tributaries. It is one of three species of cooters (''Pseudemys'') occurring in Texas, including the Rio Grande cooter ('' Pseudemys gorzugi'') and the river cooter (''Pseudemys concinna'').Dixon, James R. (2013). Amphibians and Reptiles of Texas: with Keys, Taxonomic Synopses, Bibliography, and Distribution Maps. Texas A&M University Press, College Station, Texas. viii, 447 pp. Description The Texas river cooter is a relatively large turtle, capable of growing to a shell length of 12+ inches (30.5 cm). They are green in color, with yellow and black markings that fade with age. Males can be distinguished from females by their longer tails, longer claws, and overall smaller size. Taxonomy The Texas cooter was once reclassified to a subspecies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georg Baur
Georg Baur (1859–1898) was a German vertebrate paleontologist and Neo-Lamarckian who studied reptiles of the Galapagos Islands, particularly the Galápagos tortoises, in the 1890s. He is perhaps best known for his subsidence theory of the origin of the Galapagos Islands, where he postulated the islands were the remains of a former landmass, connected to South America via Cocos Island. Early life and education Baur was born in Weisswasser, Bohemia in 1859. He spent his early years Hohenheim near Stuttgart. As his father was a professor of forestry, Baur initially planned to study forestry where his father was a professor. However, while at university he became interested in the fields of geology, paleontology, and botany instead. Career Prior to his work on the Galapagos Islands, Baur was an assistant to Othniel Charles Marsh at Yale University from 1884 until 1890. Baur undertook an expedition to the Galápagos Islands in 1891, leaving New York on May 1, arriving in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Claw
A claw is a curved, pointed appendage found at the end of a toe or finger in most amniotes (mammals, reptiles, birds). Some invertebrates such as beetles and spiders have somewhat similar fine, hooked structures at the end of the leg or tarsus for gripping a surface as they walk. The pincers of crabs, lobsters and scorpions, more formally known as their chelae, are sometimes called claws. A true claw is made of a hard protein called keratin. Claws are used to catch and hold prey in carnivorous mammals such as cats and dogs, but may also be used for such purposes as digging, climbing trees, self-defense and grooming, in those and other species. Similar appendages that are flat and do not come to a sharp point are called nails instead. Claw-like projections that do not form at the end of digits but spring from other parts of the foot are properly named spurs. Tetrapods In tetrapods, claws are made of keratin and consist of two layers. The unguis is the harder external layer, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Texas
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiles Of The United States
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 around 31 ...

Pseudemys Texana2
''Pseudemys'' is a genus of large, herbivorous, freshwater turtles of the eastern United States and adjacent northeast Mexico. They are often referred to as cooters, which stems from ''kuta'', the word for turtle in the Bambara and Malinké languages, brought to America by enslaved people from Africa. Etymology The generic name ''Pseudemys'' is derived from the Greek words, ''pseudes'' meaning false or misleading, and ''emydos'' a freshwater turtle, implying a resemblance to, but not included in the genus ''Emys''.Seidel, Michael and Carl H. Ernst. 1996. Pseudemys'' Catalogue of American Amphibians and Reptile. Society for the Study of Amphibians and Reptiles. 625: 1-7 pp. The trivial names, or specific epithets, of five of the species are toponyms, named for places where the species were first discovered including, the Florida peninsular (''P. peninsularis''),Seidel, Michael and Carl H.

Red-eared Slider
The red-eared slider or red-eared terrapin (''Trachemys scripta elegans'') is a subspecies of the pond slider (''Trachemys scripta''), a semiaquatic turtle belonging to the family Emydidae. It is the most popular pet turtle in the United States, is also popular as a pet across the rest of the world, and is the most invasive turtle. It is the most commonly traded turtle in the world. The red-eared slider is native from the Midwestern United States to northern Mexico, but has become established in other places because of pet releases, and has become invasive in many areas where it outcompetes native species. The red-eared slider is included in the list of the world's 100 most invasive species. Etymology The red-eared slider gets its name from the small, red stripe around its ears, or where its ears would be, and from its ability to slide quickly off rocks and logs into the water. This species was previously known as Troost's turtle in honor of an American herpetologist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
