The Big-headed turtle is a distinctive freshwater species recognized for its unusually large head, which it is unable to retract into its shell due to its size. This turtle possesses a powerful bite and a notably long tail, often nearly equal in length to its body. Remarkably agile, the Big-headed Turtle can climb steep, rocky surfaces—including waterfalls—by utilising its strong jaws and limbs.
The Big-headed turtle is endangered due to habitat loss, illegal pet trade, and overharvesting for traditional medicine and food markets in parts of Asia.
The Big-headed Turtle is unable to pull their head into their shell due to its unusually large size. In fact, the head remains prominently exposed even when the turtle attempts to withdraw, leaving it vulnerable to predators. As a result, the species relies on its powerful bite and remarkable agility as primary means of defence.
Big-headed turtles are native to mountainous forest streams in Southeast Asia, including southern China, northern Thailand, Laos, Cambodia, and Vietnam.
