Chelonoidis
''Chelonoidis'' is a genus of turtles in the tortoise family erected by Leopold Fitzinger in 1835. They are found in South America and the Galápagos Islands, and formerly had a wide distribution in the West Indies. The multiple subspecies of the Galápagos tortoise are among the largest extant terrestrial chelonians. Giant members of the genus, such as Lutz's giant tortoise (''C. lutzae'') were also present in mainland South America and the West Indies during the Pleistocene. Taxonomy They were formerly assigned to '' Geochelone'', but a 2006 genetic analysis indicated that they were actually most closely related to hingeback tortoises. However, a more recent genetic analysis of mtDNA has found that they are actually most closely related to the lineage containing '' Centrochelys'' and '' Geochelone''. Their ancestors apparently floated across the Atlantic from Africa to South America in the Oligocene. This crossing was made possible by their ability to float with their h ...

Galápagos Tortoise
The Galápagos tortoise or Galápagos giant tortoise (''Chelonoidis niger'') is a species of very large tortoise in the genus ''Chelonoidis'' (which also contains three smaller species from mainland South America). It comprises 15 subspecies (13 extant and 2 extinct). It is the largest living species of tortoise, with some modern Galápagos tortoises weighing up to . With lifespans in the wild of over 100 years, it is one of the longest-lived vertebrates. Captive Galapagos tortoises can live up to 177 years. For example, a captive individual, Harriet, lived for at least 175 years. Spanish explorers, who discovered the islands in the 16th century, named them after the Spanish '' galápago'', meaning "tortoise". Galápagos tortoises are native to seven of the Galápagos Islands. Shell size and shape vary between subspecies and populations. On islands with humid highlands, the tortoises are larger, with domed shells and short necks; on islands with dry lowlands, the tortoises ...

Red-footed Tortoise
The red-footed tortoise (''Chelonoidis carbonarius'') is a species of tortoise from northern South America. These medium-sized tortoises generally average as adults, but can reach over . They have dark-colored, loaf-shaped carapaces (back shell) with a lighter patch in the middle of each scute (scales on the shell), and dark limbs with brightly colored scales that range from pale yellow to dark red. Recognized differences are seen between red-footed tortoises from different regions. They are closely related to the yellow-footed tortoise (''C. denticulatus'') from the Amazon Basin. They are popularly kept as pets, and over-collection has caused them to be vulnerable to extinction.The species name has often been misspelled as ''carbonaria'', an error introduced in the 1980s when ''Chelonoidis'' was elevated to genus and mistakenly treated as feminine, an error recognized and fixed in 2017. Their natural habitat ranges from savannah to forest edges around the Amazon Basin. They a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chaco Tortoise
The Chaco tortoise (''Chelonoidis chilensis''), also known commonly as the Argentine tortoise, the Patagonian tortoise, or the southern wood tortoise, is a species of tortoise in the family Testudinidae. The species is endemic to South America. Geographic range The Chaco tortoise is mainly found in Argentina, but also in Bolivia and Paraguay, mainly within the Chaco and Monte ecoregions. Its distribution is mainly limited by temperature-related variables, and precipitation in the reproductive period. Taxonomy The scientific name for this species, ''Chelonoidis chilensis'', is misleading because it is not native to Chile. It occurs mainly in Argentina, Bolivia and neighboring Paraguay. When the species was first described by Gray in 1870, he mistakenly thought that Mendoza was in Chile instead of Argentina ( the city was transfer in 1776), thus the misnomer. Sclater corrected Gray's mistake in the same year. However, the rules of nomenclature give precedence to the name ''chile ...

Yellow-footed Tortoise
The yellow-footed tortoise (''Chelonoidis denticulatus''), also known as the Brazilian giant tortoise, commonly referred to as the Brazilian giant turtle, or more commonly, the big turtle, is a species of tortoise in the family Testudinidae and is closely related to the red-footed tortoise (''C. carbonarius''). 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. With an average length of 40 cm (15.75 in) and the largest known specimen at 94 cm (37 in), this is the sixth-largest tortoise species on Earth, after the Galapagos tortoise, the Aldabra tortoise, the African spurred tortoise (''Geochelone sulcata'', typical size 76 cm (30 in)), the leopard tortoise (''Stigmochelys pardalis''), and the Asian forest tortoise (''Manouria emys emys'', ...

Tortoise
Tortoises () are reptiles of the family Testudinidae of the order Testudines (Latin: ''tortoise''). 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. Tortoises can vary in size with some species, such as the Galápagos giant tortoise, growing to more than in length, whereas others like the Speckled cape tortoise have shells that measure only long. Several lineages of tortoises have independently evolved very large body sizes in excess of 100 kg, including the Galapagos giant tortoise and the Aldabra giant tortoise. They are usually diurnal animals with tendencies to be crepuscular depending on the ambient temperatures. They are generally reclusive animals. Tortoises are the longest-living land animals in the world, although the longest-living specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chelonoidis Alburyorum
''Chelonoidis alburyorum'' is an extinct species of land tortoise that lived from the late Pleistocene to around 1400 CE. The species was discovered and described by Richard Franz and Shelley E. Franz, the findings being published in 2009. Name The specific epithet, ''alburyorum'', is in honor of Bahamian naturalist Nancy Ann Albury. Fossil The shell of ''C. alburyorum'' was 47 cm (19 inches) in length. Fossils of the species were discovered in Sawmill Sink, a blue hole. Other sites where ''C. alburyorum'' fossils have been found include cave systems and an inland deep blue sink hole. All fossils of ''C. alburyorum'' have been found in the Bahamas. Extinction ''C. alburyorum'' was the last-surviving of the West Indian ''Chelonoidis'', persisting up to 1170 CE on the Abacos, up to 1200 CE on Grand Turk, and up to 1400 CE on the Middle Caicos Middle Caicos is the largest island in the Turks and Caicos Islands. To the west, it is separated from North Caicos by Juniper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galápagos Islands
The Galápagos Islands ( es, Islas Galápagos) are an archipelago of volcanic islands in the Eastern Pacific, located around the Equator west of the mainland of South America. They form the Galápagos Province of the Republic of Ecuador, with a population of slightly over 33,000 (2020). The province is divided into the Cantons of Ecuador, cantons of San Cristóbal Island, San Cristóbal, Santa Cruz Island (Galápagos), Santa Cruz, and Isabela Island (Galápagos), Isabela, the three most populated islands in the chain. The Galápagos are famous for their large number of Endemism, endemic species, which were studied by Charles Darwin in the 1830s and inception of Darwin's theory, inspired his theory of evolution by means of natural selection. All of these islands are protected as part of Ecuador's Galápagos National Park and Galápagos Marine Reserve, Marine Reserve. Thus far, there is no firm evidence that Polynesian expansion, Polynesians or the indigenous peoples of South Am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geochelone
''Geochelone'' is a genus of tortoises. ''Geochelone'' tortoises, which are also known as typical tortoises or terrestrial turtles, can be found in southern Asia. They primarily eat plants. Species The genus consists of two extant species: A number of tortoise species have been recently removed from the genus. This taxon as formerly defined was "polyphyletic, representing at least five independent clades". Tortoises removed include members of ''Aldabrachelys'' (from the Seychelles and Madagascar), ''Astrochelys'' (Madagascar), ''Chelonoidis'' (South America and the Galápagos Islands), ''Stigmochelys'' and ''Centrochelys'' (Africa), and the extinct ''Megalochelys'' (southern Asia). These species are also unique for their ability to remember patterns and spatial pathways. Similar to mammals, these tortoises can remember directions and pathways by remembering the correct pathways in their long-term memory.
