Astrochelys Yniphora
The angonoka tortoise (''Astrochelys yniphora'') is a critically endangered species of tortoise severely threatened by poaching for the illegal pet trade. It is endemic to Madagascar. It is also known as the angonoka, ploughshare tortoise, Madagascar tortoise, or Madagascar angulated tortoise. There may be fewer than 400 of these tortoises left in the wild. It is found only in the dry forests of the Baly Bay area of northwestern Madagascar, near the town of Soalala (including Baie de Baly National Park). A captive-breeding facility was established in 1986 by the Jersey Wildlife Preservation Trust (now the Durrell Trust) in collaboration with the Water and Forests Department. In 1996, 75 tortoises were stolen, which later appeared for sale in the Netherlands. The project was ultimately successful, achieving 224 captive-bred juveniles out of 17 adults in 2004. Project Angonoka developed conservation plans that involved local communities making firebreaks, along with the creation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astrochelys Radiata
The radiated tortoise (''Astrochelys radiata'') 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. Description Adults typically have a carapace length of and weigh . The largest individuals tend to be males. This species has the basic "tortoise" body shape, which consists of the high-domed carapace, a blunt head, and elephantine feet. The legs, feet, and head are yellow except for a variably sized black patch on top of the head. The carapace of the radiated tortoise is brilliantly marked with yellow lines radiating from the center of each dark plate of the shell, henc ...

Astrochelys Rogerbouri
''Astrochelys rogerbouri'' is an extinct tortoise species in the family Testudinidae which formerly lived in Madagascar. Discovery and naming The type specimen, MNHN.F.MAD480, is a nearly complete tibia and was collected in June 1900 in Ambolisatra, Madagascar by Guillaume Grandidier. It is kept at the Muséum national d’histoire naturelle. This material was originally assigned as a juvenile specimen of '' Aldabrachelys abrupta'', likely as the two share a type locality, and it was only found to represent a new species after DNA analysis. The specific name honors Roger Bour, a herpetologist and expert on western Indian Ocean giant tortoises who helped in the investigation describing this species. Description ''Astrochelys rogerbouri'' was a large tortoise species, with an estimated straight carapace length of . This matches the size of its congeneric relative, the angonoka tortoise, which has a maximum straight carapace length of . Though it is only known from a tibia, it ...

Testudinidae
Tortoises ( ) are reptiles of the family Testudinidae of the order Testudines (Latin for "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 , 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 species of tortoise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic Fauna Of Madagascar
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Reptiles Of Madagascar
Reptiles, as commonly defined, are a group of tetrapods with an ectothermic metabolism and amniotic development. Living traditional reptiles comprise four orders: Testudines, Crocodilia, Squamata, and Rhynchocephalia. About 12,000 living species of reptiles are listed in the Reptile Database. The study of the traditional reptile orders, customarily in combination with the study of modern amphibians, is called herpetology. Reptiles have been subject to several conflicting taxonomic definitions. In Linnaean taxonomy, reptiles are gathered together under the class Reptilia ( ), which corresponds to common usage. Modern cladistic taxonomy regards that group as paraphyletic, since genetic and paleontological evidence has determined that birds (class Aves), as members of Dinosauria, are more closely related to living crocodilians than to other reptiles, and are thus nested among reptiles from an evolutionary perspective. Many cladistic systems therefore redefine Reptilia as a cla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...
