First, distinguish from the appearance:
The turtle's shell is cracked, and the turtle's shell is basically a whole, which is actually easy to distinguish from the shape of the shell; The shell of a turtle is much harder than that of a turtle. I used to have two little turtles at home. Later, when the tortoise grew up, it was no problem for a child weighing 30 to 40 kilograms to stand on a turtle shell, and the turtle shell was very hard. Then the turtle shell is convex and round, and the turtle shell is flat. There is a skirt on the turtle shell, which can be said to be the best place to eat on the turtle, full of collagen.
Second, distinguish from living habits:
Turtles can't stay out of water for long. Turtles generally live in mud at the bottom of the water and like to steal holes in the water. Turtles can live for a long time without drinking water, sleep, and live for a long time without eating or drinking; Turtles and soft-shelled turtles are fierce carnivores, especially turtles are more fierce than soft-shelled turtles. Don't be fooled by its simple appearance. Being bitten really hurts. Don't ask me why.
Brief introduction of soft-shelled turtle and tortoise;

The head is small, not as wide as 1/4 of the posterior nail, the front of the head is smooth, and the skin at the back has fine granular scales; The snout is obliquely cut inward, and the horny sheath at the beak edge is thin; The angle between the left and right odontoid bones of mandible is less than 90.
