Spider Tortoise
The spider tortoise (''Pyxis arachnoides'') is a species of tortoise in the family Testudinidae that is endemic to Madagascar and is one of only two species in the genus ''Pyxis''. Habitat The remaining tortoises are found only in south western Madagascar Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa ..., where they inhabit the spiny vegetation of the sandy coastal areas. Life cycle and breeding Very little is known about the life cycle of this endangered tortoise, which is believed to live for up to 70 years. Here they feed on young leaves, insect larvae, and even the droppings of larger animals. When the wet season arrives, the dormancy period ends and the tortoises begin to mate. Females only lay one egg when they reproduce, and the egg is incubated for about 220–250 days. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tortoise
Tortoises () are reptiles of the family Testudinidae of the order Testudines (Latin: ''tortoise''). Like other turtles, tortoises have a turtle shell, 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 tortoise, Galápagos giant tortoise, growing to more than in length, whereas others like the Chersobius signatus, Speckled cape tortoise have shells that measure only long. Several lineages of tortoises Giant tortoise, have independently evolved very large body sizes in excess of 100 kg, including the Galápagos tortoise, Galapagos giant tortoise and the Aldabra giant tortoise. They are usually Diurnality, diurnal animals with tendencies to be crepuscular depending on the ambient temperatures. They are generally reclusive animals. ...

Flat-backed Spider Tortoise
The flat-backed spider tortoise (''Pyxis planicauda''), more commonly known as the flat-tailed tortoise, and Madagascan flat-tailed tortoise, is a tortoise that belongs to the family Testudinidae. The various common names for this small tortoise usually refer to the noticeably flattened nature of its oblong upper-shell or its tail. The flat-backed spider tortoise is endemic to the west coast of Madagascar, between the Monrondava and Tsiribihina rivers. Due to the specifications of its habitat, the flat-backed spider tortoise is classified as critically endangered on the IUCN Red List. Description The flat-backed spider tortoise receives its name from its distinctive physical appearance. Its upper-shell (carapace) and tail are outstandingly flatter than the common tortoise. Its carapace is patterned, with each scute ranging in color from light brown to yellow center and a dark brown to black outline. In older tortoise, an additional yellow border can be seen that surrounds the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Turtle Genera
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 plates th ...
