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] |
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 ...

Testudines
Turtles are an order of reptiles known as Testudines, characterized by a special shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. Turtle shells are made mostly of bone; the upper part is the domed carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scales made of keratin, the material of hair, horns, and claws. The carapace bones develop from ribs that grow sideways and develop into broad flat plat ...

Giant Tortoise
Giant tortoises are any of several species of various large land tortoises, which include a number of extinct species, as well as two extant species with multiple subspecies formerly common on the islands of the western Indian Ocean and on the Galápagos Islands. History As of March 2022, two different species of giant tortoise are found on two remote groups of tropical islands: Aldabra Atoll and Fregate Island in the Seychelles and the Galápagos Islands in Ecuador. These tortoises can weigh as much as and can grow to be long. Giant tortoises originally made their way to islands from the mainland via oceanic dispersal. Tortoises are aided in such dispersal by their ability to float with their heads up and to survive for up to six months without food or fresh water. Giant tortoises were once all placed in a single genus (often referred to as ''Testudo'' or ''Geochelone''), but more recent studies have shown that giant tortoises represent several distinct lineages that are n ...

Aldabra Giant Tortoise
The Aldabra giant tortoise (''Aldabrachelys gigantea'') is a species of tortoise in the family Testudinidae. The species is endemic to the islands of the Aldabra Atoll in the Seychelles. It is one of the largest tortoises in the world.Pritchard, Peter C.H. (1979) ''Encyclopedia of Turtles.'' Neptune, New Jersey: T.F.H. Publications, Inc. Ltd. Historically, giant tortoises were found on many of the western Indian Ocean islands, as well as Madagascar, and the fossil record indicates giant tortoises once occurred on every continent and many islands with the exception of Australia and Antarctica. Many of the Indian Ocean species were thought to be driven to extinction by over-exploitation by European sailors, and they were all seemingly extinct by 1840 with the exception of the Aldabran giant tortoise on the island atoll of Aldabra. Although some remnant individuals of ''A. g. hololissa'' and ''A. g. arnoldi'' may remain in captivity, in recent times, these have all been reduced as s ...

Leopard Tortoise (Stigmochelys Pardalis) Head
The leopard tortoise (''Stigmochelys pardalis'') is a large and attractively marked tortoise found in the savannas of eastern and southern Africa, from Sudan to the southern Cape. 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 holes. 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. Taxonomy and etymology The phylogenic placement of the leopard tortoise has been subject to several revisions. Different authors have placed it in ''Geochelone'' (1957), ''Stigmochelys'' (2001), ''Centrochelys'' (2002), and ''Psammobates'' (2006). More recently, consensus appears to have settled on ...

Chersobius Signatus
''Chersobius signatus'' is the world's smallest species of tortoise (family Testudinidae). The species is commonly known as the speckled tortoise and also known locally as the speckled padloper and internationally as the speckled Cape tortoise. A member of the genus '' Chersobius'', it is endemic to South Africa.Homopus Research Foundation web site (accessed August 24, 2013). Distribution and subspecies ''C. signatus'' is naturally restricted to a small area in Little Namaqualand, an arid region in the west of South Africa, where it normally lives on rocky outcrops and forages among the rocks for the tiny succulent plants it eats.

Box Turtle
Box turtle is the common name for several species of turtle. It may refer to those of the genus '' Cuora'' or '' Pyxidea'', which are the Asian box turtles, or more commonly to species of the genus '' Terrapene'', the North American box turtles. They are largely characterized by having a shell shaped like a dome, which is hinged at the bottom, allowing the animal to close its shell tightly to escape predators. Furthermore, the two genera are very different in habitat, behavior and appearance, and are not even classified in the same family. Even though box turtles became very popular pets, their needs in captivity are complex and the capture of turtles can have serious detrimental effects on the wild population. The box turtle commonly lives over twenty years, with verified cases of lifespans exceeding 40 to 50 years. There have been unverified cases of box turtles living for a hundred years and more. Diet Box turtles are omnivorous. Their eagle eyes and keen sense of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiles
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 originat ...

Adwaita
Adwaita (meaning "one and only" in Sanskrit) (c. 1750 – 22 March 2006), also spelled Addwaita, was a male Aldabra giant tortoise that lived in the Alipore Zoological Gardens of Kolkata, India. At the time of his death in 2006, Adwaita was believed to be amongst the longest-living animals in the world. He may have been from Aldabra, an atoll in the Seychelles. This anecdotal report has not been confirmed. The animal was one of four tortoises that lived at Robert Clive's estate at Barrackpore, in the northern suburbs of Calcutta. Clive was said to have received the tortoises following his victory at the Battle of Plassey in 1757, in which the British East India Company defeated the Nawab of Bengal and his French allies, thereby securing India for Britain in the long run. Adwaita was transferred to the Alipore Zoo in Calcutta in 1875 or 1876 by Carl Louis Schwendler, the founder of the zoo. Adwaita lived in his enclosure in the zoo until his death on 22 March 2006 at an estimate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diamondback Terrapin
The diamondback terrapin or simply terrapin (''Malaclemys terrapin'') is a species of turtle native to the brackish coastal tidal marshes of the Northeastern and southern United States, and in Bermuda. It belongs to the monotypic genus ''Malaclemys''. It has one of the largest ranges of all turtles in North America, stretching as far south as the Florida Keys and as far north as Cape Cod. The name "terrapin" is derived from the Algonquian word . It applies to ''Malaclemys terrapin'' in both British English and American English. The name originally was used by early European settlers in North America to describe these brackish-water turtles that inhabited neither freshwater habitats nor the sea. It retains this primary meaning in American English. In British English, however, other semi-aquatic turtle species, such as the red-eared slider, might also be called terrapins. Description The common name refers to the diamond pattern on top of its shell (carapace), but the overall p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
