Sacalia
''Sacalia'' is a genus of turtles in the family Geoemydidae (formerly Bataguridae). The genus was erected by John Edward Gray in 1870. The Sacalia is native to Southereastern China, Laos, and Vietnam. It was declared an endangered turtle species by the IUCN Red List due to its illegal trade. The sacalia has a carapace of dark-brown color that permits it to camouflage to its habitat. They are believed to select the area of a river that better matches their color.

Four-eyed Turtle
The four-eyed turtle (''Sacalia quadriocellata'') is a reptile of the order Testudines. Its name refers to two bright yellow or green spots that occur on the back of its head that can look like another pair of eyes. Geographic range This species of turtle occurs in southern China and Hainan, in the Annamite Mountains and northeastern region of Laos, and in the mountains of northern and central Vietnam. Hybridization A male of this species has successfully produced hybrids with the Golden coin turtle in captivity. Given that the "four-eye" pattern is inherited by these hybrids, it seems well possible that the mysterious Chinese false-eyed turtle (''Sacalia pseudocellata'') is actually based on a hybrid specimen. Description The four-eyed turtle can grow to a carapace length of . Its carapace typically ranges in color from a yellowish-tan to a deep chocolate-brown, and all turtles have a distinct pattern of lines. The turtle's head is often colorful with yellow or green eyes, y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beale's Eyed Turtle
Beale's eyed turtle (''Sacalia bealei'') is a species of turtle in the family Geoemydidae (formerly Bataguridae). The species is endemic to China. Description ''S. bealei'' has a yellowish-brown, smooth, rather depressed carapace spotted with black, and it has an olive-green head. Another form of this species has a brown carapace. In both forms, there are two pairs of black-centered ocelli on the back of the head which is peppered with black spots. This is a turtle of moderate size and will grow up to a maximum straight-line carapace length of 18 cm (7 inches). Habitat A nocturnal species, ''S. bealei'' lives in mountain streams at all elevations, but with a preference for heavily forest-covered streams with many large stones so as to provide shelter. Diet ''S. bealei'' feeds on crayfish and worms, and accepts meat in captivity. Behavior A timid and nervous species, ''S. bealei'' will scramble and flail wildly with its claws when handled. Reproduction ''S. bealei'' is repo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese False-eyed Turtle
The Chinese false-eyed turtle (''Cuora trifasciata × Sacalia quadriocellata'') is a hybrid species of turtle in the family Geoemydidae. It is a hybrid between a male golden coin turtle (''Cuora trifasciata'') and a female four-eyed turtle (''Sacalia quadriocellata''). While formerly considered to be a wild type species believed to be originally from Hainan, it is now known only from pet trade type specimens.

Geoemydidae
The Geoemydidae (formerly known as Bataguridae) are one of the largest and most diverse families in the order Testudines (turtles), with about 70 species A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), .... The family includes the Eurasian pond and river turtles and Neotropical wood turtles. Characteristics Geoemydidae are turtles of various sizes (from about in length) with often a high degree of sexual dimorphism. They usually have webbed toes, and their pelvic girdles articulate with their plastrons flexibly. Their necks are drawn back vertically. Their carapaces have 24 marginal scutes. The plastron is composed of 12 scutes and has no mesoplastron; the pectoral and abdominal scutes contact the marginal scutes. Some other features include a single articulation betwee ...

Cuora Trifasciata
__NOTOC__ The golden coin turtle (''Cuora trifasciata''), also known Common name, commonly as the Chinese three-banded box turtle and the Chinese three-striped box turtle, is a species of turtle in the Family (biology), family Geoemydidae. The species is native to southern China. Is has two recognized subspecies. Geographic range ''C. trifasciata'' is distributed in China, but only on the island of Hainan (it is extirpated from the mainland Guangdong, Guangxi, and Fujian provinces), as well as Hong Kong. The populations from Vietnam and Laos are now regarded as a separate species, the Vietnamese three-striped box turtle (''C. cyclornata''). Description ''C. trifasciata'' has three distinct black stripes on its brown carapace, with a yellow, slightly hooked upper jaw and a yellow stripe extending from the back of the mouth. The plastron is mostly black with a yellow border. Subspecies Two subspecies are recognized as being valid, including the nominotypical subspecies. *''Cuora t ...

John Edward Gray
John Edward Gray (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Turtle
Turtles are reptiles of the order (biology), order Testudines, characterized by a special turtle shell, 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 Amniote, 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 Turtle shell#Carapace, carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scale (anatomy), scales made of keratin, the material of hair, horns, and claws. The carapace bones deve ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
