Morphological Characteristics, Living Habits, and Conservation Status of the Big-headed Turtle

The big-headed turtle is the representative species of the family Platysternidae in the order Testudines. It gets its name because its head is broad and cannot be retracted into its shell, and it is also commonly known among the public as the eagle-beaked turtle or big-headed turtle. It is mainly distributed in the mountain streams of southern China and some parts of Southeast Asia, and it prefers to inhabit shallow-water environments with clear water quality and relatively fast currents.

This turtle's appearance is very easy to identify: the upper beak is curved in the shape of an eagle's beak, the top of the head is covered by a single whole horny hard shield, the limbs are stout and webbed, and the tail is slender, approaching the length of the carapace. Although its body size is not particularly large, its temperament is rather fierce and its bite force is strong, and when in danger it often relies on its powerful lower jaw for self-defense. The big-headed turtle's climbing ability is quite outstanding among turtles, and it can move agilely among the jumbled rocks of streams.

In terms of diet, the big-headed turtle is a turtle that tends toward carnivory, mostly active at night or dusk, and often preys on snails, shrimp and crabs, small fish, and insects in streams. It is relatively sensitive to water temperature and water quality, and is suited to living in cool, clean flowing water; therefore, artificial keeping is fairly difficult and requires simulating a stream environment close to nature.

Because its wild population has been continuously declining, the big-headed turtle has been included in China's List of National Key Protected Wild Animals and is a national second-class protected animal, and catching and trading it at will are illegal acts. Friends interested in this turtle can learn relevant knowledge through proper channels and join in protecting this unique stream species.
