A tetrapod is any four-limbed vertebrate animal of the superclass Tetrapoda. Tetrapods include all extant and extinct amphibians and amniotes, with the latter in turn evolving into two major clades, the sauropsids and synapsids. Some tetrapods such as snakes, legless lizards, and caecilians have evolved to become limbless via mutations of the Hox gene, although some do still have a pair of vestigial spurs that are remnants of the hindlimbs.
Herpetology is a branch of zoology concerned with the study of amphibians and reptiles. Birds, which are cladistically included within Reptilia, are traditionally excluded here; the separate scientific study of birds is the subject of ornithology.
Leonhard Hess Stejneger was a Norwegian-born American ornithologist, herpetologist and zoologist. Stejneger specialized in vertebrate natural history studies. He gained his greatest reputation with reptiles and amphibians.
The Blanding's turtle is a semi-aquatic turtle of the family Emydidae. This species is native to central and eastern parts of Canada and the United States. It is considered to be an endangered species throughout much of its range. The Blanding's turtle is of interest in longevity research, as it shows few or no common signs of aging and is physically active and capable of reproduction into eight or nine decades of life.
The smooth snake is a species of non-venomous snake in the family Colubridae. The species is found in northern and central Europe, but also as far east as northern Iran. The Reptile Database recognizes two subspecies as being valid, including the nominotypical subspecies described here.
"Labyrinthodontia" is an informal grouping of extinct predatory amphibians which were major components of ecosystems in the late Paleozoic and early Mesozoic eras. Traditionally considered a subclass of the class Amphibia, modern classification systems recognize that labyrinthodonts are not a formal natural group (clade) exclusive of other tetrapods. Instead, they consistute an evolutionary grade, ancestral to living tetrapods such as lissamphibians and amniotes. "Labyrinthodont"-grade vertebrates evolved from lobe-finned fishes in the Devonian, though a formal boundary between fish and amphibian is difficult to define at this point in time.
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.
The northern sheep frog is native to Central America, Mexico, and extreme south Texas, United States. It occurs in the lowlands from Sonora, Mexico, to northern Costa Rica on the Pacific coast, and south Texas to Honduras on the Gulf of Mexico and Caribbean coasts. The sheep frog inhabits semiarid thornscrub, savannas, pasturelands, and open woodlands, as well as more humid, moist forest in the canyons, basins, foothills, and lower elevations of mountains slopes. It is a fossorial, burrowing frog that is seldom seen on the surface except at night after heavy rains when they emerge to breed. The sheep frog gets its name from its distinctive call that resembles a sheep's bleat. It is a diet specialist primarily feeding on termites and ants.
Karl Patterson Schmidt was an American herpetologist.
Hobart Muir Smith, born Frederick William Stouffer, was an American herpetologist. He is credited with describing more than 100 new species of American reptiles and amphibians. In addition, he has been honored by having at least six species named after him, including the southwestern blackhead snake, Smith's earth snake, Smith's arboreal alligator lizard, Hobart's anadia, Hobart Smith's anole, and Smith's rose-bellied lizard. At 100 years of age, Smith continued to be an active and productive herpetologist. Although he published on a wide range of herpetological subjects, his main focus throughout his career was on the amphibians and reptiles of Mexico, including taxonomy, bibliographies, and history. Having published more than 1,600 manuscripts, he surpassed all contemporaries and remains the most published herpetologist of all time.
The western hognose snake is a species of snake in the family Colubridae. The species is endemic to North America. There are three subspecies that are recognized as being valid, including the nominotypical subspecies.
Storeria dekayi, commonly known as De Kay's brown snake, De Kay's snake, and simply the brown snake, is a small non-venomous species of snake in the family Colubridae. The species is native to North America and Central America.
The plains garter snake is a species of garter snake native to most of the central United States as far north as Canada and as far south as Texas. It has a distinctive orange or yellow stripe from its head to tail, and the rest of its body is mainly a gray-green color. The snake is commonly found living near water sources such as streams and ponds, but can also be found in urban areas and vacant lots. Although the IUCN lists the species as "Least Concern", some states have given it their own special status. This species is mildly venomous, although the venom is not toxic to humans.
Drymobius margaritiferus, commonly known as the speckled racer, is a species of nonvenomous colubrid snake native to the Americas. The specific name, margaritiferus, means "pearl-bearing" in Latin, referring to the pearl-like spots on the dorsal scales.
The Rio Grande cooter is a species of turtle in the family Emydidae. The species is native to northeastern Mexico and the adjacent southwestern United States.
Ctenosaura similis, commonly known as the black iguana or black spiny-tailed iguana, is an iguanid lizard native to Mexico and Central America. It has been reported in some Colombian islands in the Caribbean Sea and Pacific Ocean, and has been introduced to the United States in the state of Florida. The largest species in the genus Ctenosaura, it is commonly found in areas such as grasslands and forests.
Alexander Mikhailovich Nikolsky was a Russian and Ukrainian zoologist born in Astrakhan.
Martha L. "Marty" Crump is a behavioral ecologist in the Department of Biology and the Ecology Center at Utah State University who studies amphibians and reptiles. Crump was the first individual to perform a long-term ecological study on a community of tropical amphibians, and did pioneering work in the classification of variability in amphibian egg size as a function of habitat predictability. She has co-authoried one of the most popular modern herpetology textbooks, Herpetology (1997–2015) as well as the memoir In Search of the Golden Frog (2000) and a number of other books for both adults and children. In 1997, she received the Distinguished Herpetologist Award from The Herpetologists’ League.
Albert Schwartz was an American zoologist who worked extensively with the herpetofauna of Florida and the West Indies, and later with butterflies. One magazine article once dubbed him as one of the "Kings of West Indian Anole Taxonomy".
