The Black Marsh Turtle has several other common names including the Smiling Terrapin and the Siamese Temple Turtle.
It is native to much of Southeast Asia. The terrapin is found in ponds, including temple pools, marshes and lakes.
Unlike most terrapins, it is carnivorous and almost fully aquatic. Despite being also called the Bad-smelling Turtle
(it produces a foul-smelling secretion when threatened) and containing high levels of mercury pollutant, the population is
still threatened due to the food and Chinese medicine trades.
