Frog-faced softshell turtle description

GenusPelochelys (1)

With its broad head, short snout and ‘frog-like’ facial features to which it owes its name, the frog-faced softshell turtle (Pelochelys cantorii) is a distinctive, easily identified reptile (3).

The upper and lower shell, neck, and limbs of the adult frog-faced softshell turtle are an unpatterned olive-brown, whereas the juvenile may have a yellow-rimmed, dark-spotted shell and a similarly spotted head (3).

Instead of the hard exterior shell seen on most other turtles, the frog-faced softshell turtle has ribs that extend out laterally and are covered by rubbery skin, forming a soft shell (2). Like other softshell turtles in the genus Pelochelys, both the adult and juvenile have smooth shells, although sharp scales may be present on the underside of the forelimbs (3).

The frog-faced softshell turtle is the largest of the softshell turtles and has been known to grow to over two metres in length (3).

Also known as
Cantor’s giant softshell turtle.
Pelochelys cumingii, Pelochelys poljakowii.
Length: up to 2 m (2)
up to 50 kg (2)

Frog-faced softshell turtle biology

Not very much is known of the frog-faced softshell turtle’s biology as it spends much of its life buried underground with only its snout above ground (2).

The frog-faced softshell turtle tends to be an aggressive predator and feeds on a wide variety of aquatic creatures including fish and crustaceans. It has also been known to eat plants on occasion (3) (5). It has a powerful bite that can crush bone and has been described as one of the fastest striking animals on the planet, even beating the cobra (2).

The frog-faced softshell turtle nests in muddy riverbanks between February and March and lays 20 to 28 eggs per clutch. The spherical eggs measure around 30 to 35 millimetres in diameter (2) (3)


Frog-faced softshell turtle range

The frog-faced softshell turtle occurs in Southeast Asia. Its range extends from India to southern China, and south through Vietnam and Thailand to Malaysia, western Indonesia, Philippines and northern New Guinea (1) (3) (8). The northern New Guinea population possibly represents a distinct species (3).

The frog-faced softshell turtle population in Vietnam may now be extinct, and the populations in Lao People's Democratic Republic and Thailand are also believed to be teetering on the edge of extinction (4).


Frog-faced softshell turtle habitat

The frog-faced softshell turtle inhabits lowland freshwater habitats, such as inland streams, large rivers, swamps, mudflats and estuaries (3) (4)


Frog-faced softshell turtle status

The frog-faced softshell turtle is classified as Endangered (EN) on the IUCN Red List (1).

IUCN Red List species status – Endangered


Frog-faced softshell turtle threats

Habitat loss and direct exploitation are the greatest threats to the frog-faced softshell turtle (1).

The frog-faced softshell turtle is hunted for meat, eggs, decoration, pets and also as an alternative 'medicine' (4). There is a low but consistent rate of domestic trade of the frog-faced softshell turtle in most markets in coastal parts of Bangladesh and Indonesia (1), as well as a worryingly large illegal trade of these turtles from Cambodia to Vietnam (4).

In Cambodia, the frog-faced softshell turtle is easily captured by hunters who use bamboo traps or hunting dogs (4).


Frog-faced softshell turtle conservation

The frog-faced softshell turtle is currently listed on Appendix II of the Convention on International Trade in Endangered Species (CITES), which means that the trade of this extraordinary turtle should be strictly monitored to prevent overexploitation (6).

A recent discovery of the frog-faced softshell turtle nesting in abundance along the Mekong River in Cambodia in 2007 and the subsequent opening of the Mekong Turtle Conservation Centre (MTCC) in June 2011 has given scientists hope that this rare species of turtle can be saved from the brink of extinction (2) (7)

Authenticated (20/10/11) by Olivier S.G. Pauwels, Research Associate at the Royal Belgian Institute for Natural Sciences, Brussels, Belgium.

This species information was authored as part of the Arkive and Universities Scheme.


Diverse group of animals with jointed limbs and a hard external skeleton, characterised by the possession of two pairs of antennae, one pair of mandibles (mouthparts used for handling and processing food) and two pairs of maxillae (appendages used in eating, which are located behind the mandibles). Includes crabs, lobsters, shrimps, woodlice and barnacles.
A category used in taxonomy, which is below ‘family’ and above ‘species’. A genus tends to contain species that have characteristics in common. The genus forms the first part of a ‘binomial’ Latin species name; the second part is the specific name.
