Vertebrate
Vertebrates () comprise all animal taxa within the subphylum Vertebrata () (chordates with backbones), including all mammals, birds, reptiles, amphibians, and fish. Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 69,963 species described. Vertebrates comprise such groups as the following: * jawless fish, which include hagfish and lampreys * jawed vertebrates, which include: ** cartilaginous fish (sharks, rays, and ratfish) ** bony vertebrates, which include: *** ray-fins (the majority of living bony fish) *** lobe-fins, which include: **** coelacanths and lungfish **** tetrapods (limbed vertebrates) Extant vertebrates range in size from the frog species ''Paedophryne amauensis'', at as little as , to the blue whale, at up to . Vertebrates make up less than five percent of all described animal species; the rest are invertebrates, which lack vertebral columns. The vertebrates traditionally include the hagfish, which do not have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Madagascan Big-headed Turtle
The Madagascan big-headed turtle (''Erymnochelys madagascariensis'') is a turtle native to the waters of permanent slow moving rivers and lakes in western Madagascar. These turtles are critically endangered and have been evaluated to be the most endangered turtle in the world by a 2018 review. Despite their vulnerability to extinction, they are commonly eaten for food and they are still commonly shipped from Madagascar to Asia to help meet the demand of Asia's traditional medicine market. A captive breeding program has also been started to prevent the species from becoming extinct. The Turtle Conservation Fund (TCF) intends to raise US$5.6 million to cover a five-year 'Global Action Plan' which includes captive breeding and reintroduction projects, trade monitoring, new rescue centers, local conservation plans, and educational programs. Description The Madagascan big-headed turtle is one of the most endangered turtles in the world, and is also included in the Turtle Conservatio ...

The ''Bulletin'' was founded in 1881, originally for publishing short papers. One of its first editors was the American zoologist and ornithologist Joel Asaph Allen. , The Linda Hall Library of Science, Engineering & Technology, accessed 31 October 2009 Scientists and naturalists who published in the journal in its early years included Sir |
Podocnemididae
Podocnemididae is a family of pleurodire (side-necked) turtles, once widely distributed. Most of its 20 genera and 30 species are now extinct. Seven of its eight surviving species are native to South America: the genus '' Peltocephalus'', with only one species (''P. dumerilianus'', the big-headed Amazon River turtle); and the genus '' Podocnemis'', with six living species of South American side-necked river turtles. There is also one genus native to Madagascar: '' Erymnochelys'', the Madagascan big-headed turtle, whose single species ''E. madagascariensis''. Like other pleurodire turtles, podocs have a "side-necked" defensive posture, turning the head sideways to hide it under the shell. Another characteristic of pleurodires is that the pelvis is fused to the shell which prevents pelvic motion, making it difficult to walk on land. Podocnemididae turtles live in aquatic environments and have shells streamlined to aid in swimming. Taxonomy and systematics According to Ferreira ...

Pelusios
''Pelusios'' is a genus of African side-necked turtles. With 17 described species, it is one of the most diverse genera of the turtle order (Testudines). Etymology The Latin name ''Pelusios'' means "mud" or "clay", and this is reflected by the turtles habitually burying themselves to find refuge and food. Common names Common names for the genus ''Pelusios'' include hinged terrapins, African mud turtles, and mud terrapins. Taxonomy Several species have been described, with probably numerous undescribed species. The taxonomy of the genus is very confused, as these species show many local variations. Certain species, in isolated areas or with reduced populations, need to be observed as they face a distinct extinction possibility given the significant number collected by native people. Geographic range They are found throughout Sub-Saharan Africa, Madagascar, São Tomé, and the Seychelles islands. They have also been introduced on the islands of the Lesser Antilles. Descript ...

African Helmeted Turtle
The African helmeted turtle (''Pelomedusa subrufa''), also known commonly as the marsh terrapin, the crocodile turtle, or in the pet trade as the African side-necked turtle, is a species of omnivorous side-necked terrapin in the family Pelomedusidae. The species naturally occurs in fresh and stagnant water bodies throughout much of Sub-Saharan Africa, and in southern Yemen. Description The marsh terrapin is typically a rather small turtle, with most individuals being less than in straight carapace length, but one has been recorded with a length of . It has a black or brown carapace. The top of the tail and limbs are a grayish brown, while the underside is yellowish. The male turtle is distinguished by its long, thick tail. A female tends to have a shorter tail and a broader carapace. A hatchling has a shell size of about in length, and is olive to black in color. It also has two small tubercles under the chin and musk glands in the sides of the carapace. Uniquely, the gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelomedusidae
:''Alternatively, "Pelomedusidae" may refer to the Pelomedusoidea. See below for details.'' Pelomedusidae is a family of freshwater turtles endemic to sub-Saharan Africa, including Madagascar, São Tomé, and the Seychelles(Although this pop. may have been introduced by humans). They range in size from in carapace length, and are generally roundish in shape. They are unable to fully withdraw their heads into their shells, instead drawing them to the side and folding them beneath the upper edge of their shells, hence are called African side-necked turtles. The family contains two living genera. They are distinguished from their closest relatives by a hinge in the front section of the plastron.Obst, Fritz Jürgen (1998): elomedusinae ''In:'' Cogger, H.G., & Zweifel, R.G.

Hoge's Side-necked Turtle
Hoge's sideneck turtle ''(Ranacephala hogei)'' is a species of turtle in the family Chelidae. It is the only member of the genus ''Ranacephala''. The species is endemic to the eastern Atlantic Forest of Brazil, primarily in the Carangola River of Minas Gerais and Paraíba do Sul River, Rio de Janeiro. The most documented population resides in the midsection of the Carangola River with an estimated population of less than 2000. The Official Brazilian Red List considers Hoge's sideneck turtle to be the most endangered turtle species within Brazil. It was listed by the Turtle Survival Coalition as one of the world "25 Turtles in Trouble" for 2018. Etymology The specific name, ''hogei'', is in honor of Brazilian-born Belgian herpetologist Alphonse Richard Hoge. Threats The primary threat to the ongoing survival of ''R. hogei'' is habitat degradation owing to ongoing deforestation, sewage and industrial discharge, agricultural pollution Agricultural pollution refers to biot ...

Western Swamp Turtle
The western swamp turtle or western swamp tortoise (''Pseudemydura umbrina'') is a critically endangered species of freshwater turtle endemic to a small portion of Western Australia. It is the only member of the genus ''Pseudemydura'' in the monotypic subfamily Pseudemydurinae. It is the sister taxon to the subfamily Chelodininae. As a consequence of the greatly altered habitat in the area in which it occurs near Perth, Western Australia, it exists in small fragmented populations, making the species critically endangered. Taxonomy The accepted description of the species by Friedrich Siebenrock was published in 1901. The first specimen of the western swamp tortoise was collected by Ludwig Preiss in 1839 and sent to Vienna Museum. There it was labelled "New Holland" and was named ''Pseudemydura umbrina'' 1901 by Seibenrock. No further specimens were found until 1953. In 1954, Ludwig Glauert named these specimens ''Emydura inspectata'', but in 1958, Ernest Williams of Harvard U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
