Biology

provided by Arkive
The elongated tortoise is most active at dawn and dusk, its large eyes well adapted to these low light conditions (5) (6). It is an omnivore, regularly feeding on slugs and worms in addition to green leafy material and fruit (5) (6). Breeding occurs during the early part of the rainy season (5). Male elongated tortoises engage in very aggressive courtship behaviour, ramming the female and biting her vigorously around the head, neck, and front legs. The female will dig a flask shaped nest 15 to 20 centimetres deep with her back legs, in which she will lay her clutch of two to four eggs, before replacing the soil. Three clutches a season are laid when in captivity. The eggs of the elongated tortoise are large, and take 130 to 190 days to hatch (2).

Conservation

provided by Arkive
This species has been placed on Appendix II of the Convention on International Trade in Endangered Species (CITES), which regulates its legal international trade (2). Unfortunately, evident disregard for this law demonstrates that there is a desperate need for greater enforcement of protective legislation. Captive breeding programmes seems an essential conservation measure, and elongated tortoises fortunately have reproduced successfully in captivity (5) (6). Captive populations hedge against extinction, can be managed to maintain a varied gene pool, and provides possibilities for future reintroduction into the wild (6). However, before reintroduction of captive bred tortoises can be properly considered, the larger issues of international trade, disregard for protective legislation, and habitat degradation must be addressed (5).

Description

provided by Arkive
The elongated tortoise gets its common name from its distinctively long, somewhat narrow carapace (4). This shell is a caramel to dark yellowish-brown colour, with black blotches on each scute (2) (4). The head is pale yellow, except during the breeding season when both sexes develop a pink hue around the eyes and nostrils (2) (5). Males tend to be narrower than females, with shorter tails and a more concave plastron (indented underside of shell). The hind claws of the female are also markedly longer and more curved than those of the male, and are believed to be an adaptation to nest building by the female (2).

Habitat

Typically inhabiting teak forests where the humidity is high, this tortoise has also been observed basking in the hot dry conditions of open ground in India (4) (5).

Threats

provided by Arkive
This tortoise is under extreme pressure in most of its range due to it being widely harvested and sold on the Asian food markets (2). It is the most common tortoise to be shipped to the Chinese food markets from Vietnam (2); approximately 100,000 were shipped from Ho Chi Minh City in 1993 (5). Disregard for international conservation laws is apparent, with the trade in tortoises brisk, highly developed, and probably ignored by many border guards, customs officials, and airline personnel (5). Like many other tortoise species, the elongated tortoise is also sold as part of the pet trade, nearly 700 sold to the U.S. alone from 1989 to 1997, and is threatened by the habitat destruction that accompanies human commercial and residential expansion (6).

Elongated tortoise

provided by wikipedia EN

The elongated tortoise (Indotestudo elongata) is a species of tortoise found in Southeast Asia and parts of South Asia.

Description

Juvenile (584 days old)

Shell considerably depressed, more than twice as long as deep, with flat vertebral region; anterior and posterior margins slightly reverted, strongly serrated in young, feebly in old specimens; shields concentrically striated, except in old specimens; nuchal present (rarely absent), narrow and elongate; supracaudal undivided, more or less incurved; first vertebral usually nearly as long as broad in the adult, the others broader than long and nearly as broad as the costals. Plastron large, truncate anteriorly, deeply notched posteriorly; suture between the pectoral shields as long as or longer than that between the humerals; suture between the gulars as long as or a little shorter than that between the pectorals; anals forming a very short suture, or entirely separated by the anal notch; axillary and inguinal moderate. Head moderate; a pair of large praefrontal shields, usually followed by a nearly equally large frontal; beak feebly hooked, tricuspid; alveolar ridge of upper jaw short and rather feeble. Anterior face of fore limbs with moderate, unequal-sized, imbricate scales, which are largest towards the outer side; no enlarged tubercles on the thighs; tail ending in a claw-like horny tubercle. Carapace and plastron greenish yellow, each shield with an irregular black spot or blotch, which may occupy its greater portion, or may be much broken up or indistinct.[3]

Size

Typically, Indotestudo elongata are around 30 cm (12 inches) long and 3.5 kg (7 pounds) as an adult. Females tend to be wider than males and more rounded. Males also have a tail that is much larger than that of the female. The males have a concave plastron while the plastron of a female is flat. Additionally, the female's posterior claws are markedly longer and more curved than those of the male. It is believed that this is to facilitate nest building.[4]

Distribution

The species is found in India (Tripura, Jalpaiguri, East Bengal, and Singhbhum in Jharkhand), Nepal, Bangladesh, Burma (or Myanmar), Laos, Thailand (incl. Phuket), Cambodia, Vietnam, Western Malaysia, Southern China. Type locality: Arakan, Tenasserim, Burma.

Tortoise village

This species of tortoise can be seen everywhere in Ban Kok, a village in Suan Mon sub-district, Mancha Khiri district about 50 km (31.1 mi) from Khon Kaen city in Isan (northeastern) Thailand. These tortoises habitually coexisted with the villagers with nothing to harm them for more than 200 years since the village was founded. They are locally known as tao pek (เต่าเพ็ก).[5]

Threats and conservation

The elongated tortoise is a critically endangered species and is in severe decline across its natural range.[1]

The principal threats to this species are the mass harvesting of the remaining wild populations for the large and growing food markets in China and elsewhere in East Asia. It is also incorrectly believed in China that a mixture, made by grinding up the tortoise's shell, serves as an aphrodisiac.[6]

In addition, other threats are habitat destruction and illegal collecting for the pet trade.[7]

Elongated tortoises in captivity

In their natural habitat these tortoises browse a wide variety of plants. Likewise in captivity, they require a very wide range of foods, not just one type of vegetable. Their diet is principally a range of vegetables and edible leaves, however they also consume meat, snails, eggs and other food types. This serves to supplement their diet. Vegetables alone are not sufficiently varied.[8][9]

This tropical species does not survive in cold climates. Those exported to Europe and North America for the pet trade usually suffer, and soon die, if they are not given special indoor care. They also require a constant water source, for bathing and drinking. Being reptiles, which cannot control their body temperature internally, they require a varied area in which they can access both sun and shade. This allows them to move around and thus to regulate and maintain their body temperature constant.[10]
