Emydidae is a family of testudines (turtles) that includes close to 50 species in 10 genera. Members of this family are commonly called terrapins, pond turtles, or marsh turtles. Several species of Asian box turtles were formerly classified in the family; however, revised taxonomy has separated them to a different family (Geoemydidae). As currently defined, the Emydidae are entirely a Western Hemisphere family, with the exception of two species of pond turtle.
Trachemys is a genus of turtles belonging to the family Emydidae. Members of this genus are native to the Americas, ranging from the Midwestern United States south to northern Argentina, but one subspecies, the red-eared slider, has been introduced worldwide. Species under this genus are commonly referred to as sliders.
The Florida red-bellied cooter or Florida redbelly turtle is a species of turtle in the family Emydidae.
Deirochelys is a genus of freshwater turtle in the family Emydidae, the pond and marsh turtles. It contains one extant species, the chicken turtle, which is native to the southeastern United States. A second extinct member, Deirochelys carri, is known from a fossil found in Alachua County, Florida. The genus was first described by Louis Agassiz in 1857, and its name is derived from the Ancient Greek words for "neck" (deirḗ) and "tortoise" (khélūs), referring to the particularly long necks of these turtles.
Emys is a small genus within the family Emydidae. The genus, consisting primarily of freshwater pond turtles, is endemic to Europe. It is the only genus in the Emydidae outside of North America.
Chrysemys is a genus of turtles in the family Emydidae. They are found throughout most of North America.
Clemmys is a genus of turtles currently containing a single extant species, the spotted turtle (Clemmys guttata).
The Mexican box turtle is a species of box turtle belonging to the family Emydidae. It is sometimes treated as a subspecies of Terrapene carolina.
Zhou's box turtle is a species of turtle in the family Geoemydidae. The species is apparently endemic to China.
The Escambia map turtle, also known commonly as Ernst's map turtle, is a species of turtle in the family Emydidae. The species is endemic to the United States.
The Pascagoula map turtle is a species of turtle in the family Emydidae. The species is native to the southern United States.
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.
The Coahuilan box turtle, also known commonly as the aquatic box turtle, is an endangered species of turtle in the family Emydidae. Unlike the other members of the genus Terrapene, this turtle spends roughly 90% of its time in water.
The Hispaniolan slider or Haitian slider is a species of turtle in the family Emydidae found on the island of Hispaniola.
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 Taíno first went to the Bahamian islands. There is also evidence from archeological sites on San Salvador that the Taíno ate these turtles and transplanted them around the West Indies.
Actinemys is a small genus of turtles in the family Emydidae. The genus is endemic to the west coast of North America. The genus contains two species.
Terrapins are a group of several species of small turtle living in fresh or brackish water. Terrapins do not form a taxonomic unit and may not be closely related. Many belong to the families Geoemydidae and Emydidae.
The Mississippi map turtle is a subspecies of land and water turtle belonging to the family Emydidae. G. p. kohni is endemic to the central United States.
Acherontemys is an extinct genus of turtle from Eocene sediments in northwestern North America and comprising a single species Acherontemys heckmani. Acherontemys has been placed within the pond turtle superfamily Testudinoidea as part of the clade Pan-Emydidae.
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.
