Turtles are extant ancient reptiles. It is characterized by a very strong carapace on the body. When attacked, the turtle can retract the head, tail and limbs into the turtle shell. Of course, there are exceptions for some special turtle species. Turtles often live in rivers, lakes or ponds. Eat animals such as worms, snails, shrimps and small fish, and also eat plant stems and leaves and food. Because the turtle is mild and timid, keep the breeding pool quiet around, so as not to affect the normal activities of turtle feeding, sunbathing, mating, and spawning. It is necessary to change the water in the feeding pool frequently, keep the water in the pool clean, and do a good job in the hygiene of the feeding pool to prevent the turtle from developing diseases.
