1. Sharp claws: Wild turtles need to catch food by themselves, so their claws are relatively sharp. Moreover, the roots of soft-shelled turtles' claws grown in the wild are dark, but the tips are yellow. Manually bred turtles are all in cement ponds. After a long time, their claws have been blunt.

2. Clear floor color: The floor color of soft-shelled turtles grown in the wild is white and red, and the blood vessels are clear and the veins are distinct. If it is an artificially bred turtle, the color of the bottom plate is pale, and the blood vessels and veins are not very clear.

3, back pattern: Wild turtle carapace will have black pattern, but it is not obvious. If it is a turtle growing in the river, its color may be yellowish. Artificial turtles are generally in stagnant water. Because water cannot circulate and there is more silt, their color will be darker.

Turtles have very strong predation ability, their character is fierce, and their predation speed is also very fast. Turtles grown in the wild like to eat small fish, shrimp and loach, and may catch some medium-sized fish when they are hungry. Although they are fierce in character, they are still less daring. If there is a loud noise around them, they will be frightened. Therefore, soft-shelled turtles living in the wild move near the shore, and once there is a sound, they will immediately enter the water.
