Place in the ecosystem: Will eat almost anything, including fish, frogs, crabs, shrimp, insects, aquatic vegetation, and carrion. Their young and eggs provide food for water monitors.
Danger to humans: This turtle has a large head that can give a painful bite, but will not do any real damage.
Conservation status and threats: The Southeast Asian Softshell Turtle is often caught for food and for traditional Chinese medicine. It is listed as “Vulnerable” by the IUCN Red List and is on CITES Appendix II.
Interesting facts: Softshell turtles have a range of adaptations that give them a quite different appearance than other turtles. Their soft, flat shell is lighter and more streamlined so they can chase their prey through the water. The flat shell also allows them to bury easily in the mud. The long neck and narrow head can move quickly to grab prey in the water, as well as reach up to breathe while exposing none of the body. And the wide, flat feet act like paddles to propel them through the water.
