Asian Tortoises and Freshwater Turtles
Key Facts
-
Status
Some species are critically endangered
-
How many?
There are around 89 species of tortoises and turtles.
Survival threatened by illegal trade
Size
The different species vary in size, with the largest being the Burmese mountain tortoise (also known as the Asian brown tortoise). It reaches up to 60cm in length and weighs up to 20-37kg. Most Asian turtles and tortoises are sexually diamorphic, with the female being up to 10cm larger than the male.
Diet
Turtles and tortoises move too slowly to pursue active prey. Tortoises are mostly herbivores, although some species will also eat carrion. They feed on grasses, weeds, leafy greens, flowers, and some fruits. Freshwater turtles eat insects and aquatic larvae, crustaceans and aquatic vegetation.
Reproduction
Most Asian turtles and tortoises dig themselves nests in mud or sand to lay their eggs. The hatchlings are born with a tooth egg to help them break out of the shell which is shed shortly afterwards. Most species do not care for their young, leaving the eggs and hatchlings vulnerable to predators.
What are the main threats?
- Illegal wildlife trade
Despite laws and regulations aimed at protecting turtles and tortoises, illegal trade in meat and shells continues to flourish. Many end up in markets destined for import to China, Hong Kong and Japan where there is demand for meat and turtle parts for use in traditional Chinese medicine. Restrictions on the sale of these endangered species are openly flouted, and the market continues to grow. - Hunting
Local people in southern Asian countries such as Cambodia, Vietnam, Indonesia, Malaysia, Bangladesh have traditionally collected local tortoise and turtle species for food. However, higher demand, particlularly over the last decade has led to greater exploitation of this species, leading many close to extinction.
- Habitat loss & degradation
Loss of habitat through conversion to agriculture and wildfires have also had a detrimental effect on many populations.
Priority species
What is WWF doing?
- Working with governments and regulatory authorities to ensure more effective enforcement of laws and regulations
- Helping to set up and improved protected areas for endangered species
- Raising public awareness of the plight of turtles and tortoises.
- Assisting in the collection of more reliable data on turtle and tortoise trade and its impact on populations.
