The red-necked pond turtle (Mauremys nigricans) [2] is a species of turtles in the family Geoemydidae [2] endemic to China. [2] It is most likely restricted to Guangxi and Guangdong provinces, although pre-historic skull remains have been found in northern Vietnam and Hainan. [4] Other common names include Kwangtung river turtle and black-necked pond turtle. [5]

Anatomy and morphology

A megacephalic form of the red-necked pond turtle exists, commonly called 'dumb-head'. This form is rarer than the smaller headed individuals. [4] This species has strong sexual dimorphism with a significant size difference between males and females. The largest recorded male's carapace measured 185mm (7.2 in) in length whereas females with a size up to 298 mm (11.7 in) have been found. [6]

<span class="mw-page-title-main">Black softshell turtle</span> Species of turtle

The black softshell turtle or Bostami turtle, previously placed in genus Aspideretes, is a species of freshwater turtle found in India and Bangladesh. It was long believed to be inbred individuals of the Indian softshell turtle or the Indian peacock softshell turtle, but while it is a close relative of the latter, it is a distinct species. In the 1800s it was believed these turtles were brought from Iran to Chittagong shrine pond by Hazrat Bayezid Bostami. His turtles he had brought to this pond were treated as sacred and respected by the public. Previously declared extinct by the International Union for Conservation of Nature in 2002, these turtles were found still to exist in a temple's pond called the Hayagriva Madhava Temple located in Assam, and in Kalyan Sagar lake in Tripura Sundari Temple in Udaipur, Tripura, India. Through conservation methods and protection of the species, some of these turtles can be found today throughout the wild, and scientists and environmental biologists are continuing to work hard to preserve this endangered species and their natural habitat. Their mitogenome represents relatedness to 19 other species of the Testudines. When looking at the phylogenetic tree, Nilssonia Nigricans are a species represented as sisters to Nilssonia formosa.

The yellow pond turtle, is a medium-sized, semiaquatic turtle in the family Geoemydidae. This species has a characteristic broad yellow stripe extending behind the eye and down the neck; the carapace ranges in color from grayish brown to brown, and the plastron is yellow or orange with black blotches along the outer edges. It is native to East Asia, ranging from central Vietnam and Laos, north through the coastal provinces of south and central China, with insular populations known from Taiwan, Hainan and the Ryukyu Islands. Although populations in the southern Ryukyus are thought to be native, populations in the northern and central Ryukyus, as well as central Japan, are believed to have been introduced as a result of imports from Taiwan.

<span class="mw-page-title-main">Red side-necked turtle</span> Species of turtle

The red side-necked turtle, red turtle, red-footed sideneck turtle, William's toadhead turtle, or red-footed Amazon side-necked turtle is a monotypic species of turtle in the family Chelidae. It is found in Colombia and possibly Peru and Brazil. This species is dimorphic in size meaning the sexes show different characteristics. One study found that the largest female out of a group of 24 was 256 mm in carapace length. Out of that same group, the largest male was only 199 mm in carapace length. A study focused on determining how these turtles acquire their sex discovered that it is not environmentally determined rather, it is a genetic sex determination.
