Homopus femoralis, commonly known as the greater padloper, is a small tortoise of the genus Homopus , indigenous to the highveld grasslands of South Africa. [3] [4] [5] [6] [7] [8]
As its name suggests, the greater padloper is the largest of all the Homopus ("padloper") tortoises, but it is nonetheless tiny, averaging slightly over 10 cm in length – though males tend to be smaller. It has relatively large buttock tubercles. Like its close relative, H. areolatus (and unlike other padlopers), it has only four toes on its front feet as well as its hind feet.
Its shell ranges in colour from olive to reddish-brown, and is slightly flattened in both sexes. The shields tend to be separated by very thin white lines. In juveniles and adult males, the shields of the shell usually have slightly darker edges. Males can also be distinguished from females by being smaller, with longer tails. Males do not exhibit plastral concavity.
This species is sometimes confused with the Karoo padloper (H. boulengeri) which inhabits the Karoo region to the west. However greater padlopers can be distinguished not only by their larger size, but also by their nostrils which are below their eye level, by their having four toes on both their front and back feet, by the larger scales on their forelimbs, and by the darker rings around the shell scutes of many individuals. [9]
Its habitat is primarily the summer-rainfall grasslands, savanna and bushveld of the highveld plateau of southern Africa. It is found as far north as the central Free State, and as far east as the Lesotho border. It is restricted to regions of high altitude, with rainfall over 250 mm per annum.
In addition, there is a sparse relict population of greater padlopers that extends into the high escarpment on the edge of the Karoo, where the climate is relatively humid. Although it has also been known as the Karoo cape tortoise, [10] this species is not widespread in the Karoo, unlike the Karoo padloper ( Homopus boulengeri ) which is restricted to the Karoo region. [11]
Homopus femoralis is a summer-rainfall species. Within its range it tends to favour rocky outcrops, and its population is relatively sparse. It is little studied, although it appears in ITIS and other databases. [12]
The grassland species is threatened by overgrazing and poaching for the pet trade. [13] As the trade in collected Homopus species is strictly illegal and any captive specimens are systematically registered in noncommercial studbooks in South Africa and Namibia, any commercial sale of Homopus tortoises is almost without exception strictly illegal. [14]
This species does not survive for long in captivity, unless considerable effort is made to supply specimens with their natural food, that is, endemic plants from the summer-rainfall grasslands region of South Africa. This summer-rainfall tortoise also has specific temperature requirements. They spend winter under vegetation and rocks (June–September) and lay up to three eggs in summer. [15]
The eastern long-necked turtle is an east Australian species of snake-necked turtle that inhabits a wide variety of water bodies and is an opportunistic feeder. It is a side-necked turtle (Pleurodira), meaning that it bends its head sideways into its shell rather than pulling it directly back.
Chersobius signatus is the world's smallest species of tortoise. The species is commonly known as the speckled tortoise and also known locally as the speckled padloper and internationally as the speckled Cape tortoise. A member of the genus Chersobius, it is endemic to South Africa.
Oldham's leaf turtle is a species of turtle in the family Geoemydidae.
The Chaco side-necked turtle is a species of turtle in the family Chelidae. It is found in Argentina, Paraguay, and possibly Bolivia. Its natural habitat is subtropical or tropical moist montane forests. The turtle possesses long horny spurs on its upper thighs. It is 18 cm in shell length. Like other members of its genus, the turtle buries itself in the mud when the streams run dry, a behaviour possibly parallel to the winter hibernating behaviours of turtles further north.
The New Guinea snake-necked turtle is a species of turtle in the family Chelidae. The species is found almost exclusively within Western Province, Papua New Guinea.
Parker's snake-necked turtle is a species of turtle in the family Chelidae.
Pritchard's snake-necked turtle is a species of turtles in the family Chelidae. The species is endemic to a restricted area of Central Province, Papua New Guinea.
The Western New Guinea stream turtle or New Guinea snapping turtle is a species of freshwater turtle in the Chelidae family. It is found in the Bird's Head Peninsula and the Bomberai Peninsula west of Cenderawasih Bay, and on the island of Waigeo of West Papua, Indonesia.
Homopus is a genus of tiny tortoises in the family Testudinidae, endemic to southern Africa. Three species formerly included in Homopus were reclassified into the genus Chersobius, leaving two remaining as Homopus: the common padloper (H. areolatus) and the greater padloper (H. femoralis).
The six-tubercled Amazon River turtle or six-tubercled river turtle is a species of turtle in the family Podocnemididae.
The tent tortoise is a species of tortoise and one of three members of the genus, Psammobates. Known locally as the Karoo tent tortoise, this highly variable species is found in South Africa and Namibia.
Elseya dentata, the northern snapping turtle, is a large aquatic turtle found throughout many rivers in northern Western Australia and the Northern Territory. It is one of three species in the nominate subgenus Elseya.
Homopus areolatus, commonly known as the common padloper or parrot-beaked tortoise, is a tiny species of tortoise of the genus Homopus, indigenous to the southern part of South Africa.
Chersobius boulengeri, commonly known as the Karoo padloper or Boulenger's cape tortoise, is a species of tortoise in the family Testudinidae. The species is endemic to the Nama Karoo Region of South Africa.
Chelodina (Chelydera) burrungandjii, the sandstone snake-necked turtle or Arnhem Land long-necked turtle, is a medium-sized turtle reaching carapace lengths of 316 mm. The species is found in the sandstone plateaus and escarpments and the plunge pools of Arnhem Land of the Northern Territory. The species had been long recognised as valid. However, it had been difficult to research due to the remoteness of its habitat. Efforts to breed this species in captivity had been largely unsuccessful, until National Aquarium Herpetologist Matthew Benedict lead a successful breeding project in 2021. The species occurs in proximity to Chelodina rugosa, to which it is closely related. For the most part the two species are parapatric in distribution. However, they do come together in limited locations such as plunge pools at the base of the escarpments. In these areas there is hybridization between the species.
The Myanmar brown leaf turtle is a species of Asian leaf turtle found in Myanmar.
Cyclemys enigmatica, also known as the enigmatic leaf turtle, is a species of Asian leaf turtle. It is found in the Greater Sunda Islands and the Malay Peninsula.
Elseya schultzei, commonly known as Schultze's snapping turtle, is a species of chelid turtle endemic to northern New Guinea.
Chelodina (Chelydera) kuchlingi, commonly known as Kuchling's long-necked turtle or Kuchling's turtle, is a species of freshwater turtle in the family Chelidae. The species is endemic to Australia.
Chelonoidis niger phantasticus is a subspecies of Galápagos tortoise that was discovered in 1906 and thought extinct, until a single female was discovered living on Fernandina Island by an expedition in February 2019. In May 2021, a genetic test carried out by scientists from the California Academy of Sciences confirmed that the single female tortoise discovered in 2019 is from the subspecies Chelonoidis niger phantasticus. The subspecies name has often been misspelled as phantastica, an error introduced in the 1980s when Chelonoidis was elevated to genus and mistakenly treated as feminine, an error recognized and fixed in 2017.
