This species lives in ponds, creeks, swamps and marshes. It can be found in shallow, slow moving water. It is omnivorous. The main food for the turtle are insects, fish, tadpoles, leaves and seeds. The yellow pond turtle generally remains in or close to water during the day. It is usually more active at night. It usually goes onto land when it rains.
Subspecies and Hybrids.
"Mauremys mutica kami" is one of the subspecies. It is currently found in the Ryukyu Islands. There are several hybrid Asian pond turtles species. They were first described as new species but later found out as hybrid species. Fujian pond turtles ("Mauremys iversoni") are hybrid species mainly produced in Chinese turtle farms. They are produced when female yellow pond turtles and male golden coin turtles ("Cuora trifasciata") mates.
"Clemmys guangxiensis" is a hybrid species that came from the mating of "Mauremys mutica" and the Fujian pond turtle.
