The red-eared slider or red-eared terrapin is a subspecies of the pond slider, 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.
Tortoises are reptiles of the family Testudinidae of the order Testudines. Like other turtles, tortoises have a shell to protect from predation and other threats. The shell in tortoises is generally hard, and like other members of the suborder Cryptodira, they retract their necks and heads directly backward into the shell to protect them.
The mata mata, mata-mata, or matamata is a South American species of freshwater turtle found in the Amazon basin and river system of the eastern Guianas. It was formerly believed to also occur in the Orinoco basin, western Guianas and upper Rio Negro–Branco system, but in 2020 these populations were found to belong to a separate species, Chelus orinocensis. Subsequently, some authorities have modified the common name of Chelus fimbriata to Amazon mata mata. These two are the only extant species in the genus Chelus.
The marginated tortoise is a species of tortoise in the family Testudinidae. The species is endemic to Greece, Italy, and the Balkans in Southern Europe. It is the largest European tortoise. The marginated tortoise is herbivorous, and brumates for the winter.
The Greek tortoise, also known commonly as the spur-thighed tortoise or Moorish tortoise, is a species of tortoise in the family Testudinidae. Testudo graeca is one of five species of Mediterranean tortoises. The other four species are Hermann's tortoise, the Egyptian tortoise, the marginated tortoise, and the Russian tortoise. The Greek tortoise is a very long-lived animal, achieving a lifespan upwards of 125 years, with some unverified reports up to 200 years. It has the largest known genome of all reptiles.
The Russian tortoise, also commonly known as the Afghan tortoise, the Central Asian tortoise, the four-clawed tortoise, the four-toed tortoise, Horsfield's tortoise, the Russian steppe tortoise, the Soviet Tortoise, and the steppe tortoise, is a threatened species of tortoise in the family Testudinidae. The species is endemic to Central Asia from the Caspian Sea south through Iran, Pakistan and Afghanistan, and east across Kazakhstan to Xinjiang, China. Human activities in its native habitat contribute to its threatened status.
The leopard tortoise is a large and attractively marked tortoise found in the savannas of eastern and southern Africa, from Sudan to the southern Cape Province. It is the only extant member of the genus Stigmochelys, although in the past, it was commonly placed in Geochelone. This tortoise is a grazing species that favors semiarid, thorny to grassland habitats. In both very hot and very cold weather, it may dwell in abandoned fox, jackal, or aardvark burrows. The leopard tortoise does not dig other than to make nests in which to lay eggs. Given its propensity for grassland habitats, it grazes extensively upon mixed grasses. It also favors succulents and thistles.
The European pond turtle, also called commonly the European pond terrapin and the European pond tortoise, is a species of long-living freshwater turtle in the family Emydidae. The species is endemic to the Western Palearctic.
The red-footed tortoise is a species of tortoise from northern South America. These medium-sized tortoises generally average 30 cm (12 in) as adults, but can reach over 40 cm (16 in). They have dark-colored, “loaf”-shaped carapaces with a lighter patch in the middle of each scute, and a somewhat lighter-colored plastron (underbelly). They also have dark limbs dotted with brightly-colored scales, from which they get their name, that range from pale yellow to vivid or dark red. Visible differences are noted between red-footed tortoises from varying eco-regions. They are closely related to the more easterly-distributed yellow-footed tortoise of the Amazon Basin.
Testudo, the Mediterranean tortoises, are a genus of tortoises found in North Africa, Western Asia, and Europe. Several species are under threat in the wild, mainly from habitat destruction.
The golden coin turtle, also known commonly as the Chinese three-banded box turtle and the Chinese three-striped box turtle, is a species of turtle in the family Geoemydidae. The species is native to southern China. There are two recognized subspecies.
The radiated tortoise is a tortoise species in the family Testudinidae. Although this species is native to and most abundant in southern Madagascar, it can also be found in the rest of this island, and has been introduced to the islands of Réunion and Mauritius. It is a very long-lived species, with recorded lifespans of up to 188 years. These tortoises are classified as critically endangered by the IUCN, mainly because of the destruction of their habitat and because of poaching.
The Tunisian tortoise or Nabeul tortoise is a subspecies of Greek tortoises. It was originally described as a new species in 1990, and even placed in a distinct genus. The spur-thighed or "Greek" tortoises are usually collectively referred to as Testudo graeca, but this covers a wide variety of subspecies that have very different ecological and morphological characteristics and appear to comprise at least three phylogenetic lineages. As its name implies, it is found in Tunisia and nearby Algeria.
The Galápagos tortoise or Galápagos giant tortoise is a very large species of tortoise in the genus Chelonoidis. The species comprises 15 subspecies. It is the largest living species of tortoise, and can weigh up to 417 kg (919 lb). They are also the largest extant terrestrial cold-blooded animals (ectotherms).
Kleinmann's tortoise, also called commonly the Egyptian tortoise, Leith's tortoise, and the Negev tortoise, is a critically endangered species of cryptodire turtle in the family Testudinidae. The species is native to Egypt, Libya, and Israel. The species was once more widespread, but its numbers are now dwindling. The species is nearly extinct in Egypt, and complete extinction in the wild is a looming threat unless more actions are taken to protect this species.
Oskar Boettger was a German zoologist who was a native of Frankfurt am Main. He was an uncle of the noted malacologist Caesar Rudolf Boettger (1888–1976).
The yellow-footed tortoise, also known as the Brazilian giant tortoise, is a species of tortoise in the family Testudinidae and is closely related to the red-footed tortoise. It is found in the Amazon Basin of South America. The species name has often been misspelled as denticulata, an error introduced in the 1980s when Chelonoidis was elevated to genus and mistakenly treated as feminine, an error recognized and fixed in 2017.
The tent tortoise is a species of tortoise and one of three members of the genus, Psammobates. Known locally as the Karoo tent tortoise, this highly variable species is found in South Africa and Namibia.
A spur is an outgrowth of bone covered in a sheath of horn found in various anatomical locations in some animals. Unlike claws or nails, which grow from the tip of the toes, spurs form from other parts of the foot, usually in connection with joints where the toes meet the foot or the foot meets the long bones. Spurs are most commonly found on the hindfeet, though some birds possess spurs at the leading edge of the wings.
Testudo hermanni hermanni, also known as the Western Hermann's tortoise or known as the Italian tortoise, is a subspecies of tortoise. The subspecies has a rich golden yellow shell with sharp contrast. Behind the eye is a lack of a yellow patch which Testudo hermanni robertmertensi has. T. h. hermanni are located in southern France on the island of Corsica, the Balearic Islands, eastern Spain, Sicily, Sardinia, and central and south Italy.
