Why is it called a deformed turtle?

A deformed turtle looks like an ingot and is called an ingot turtle. It is not easy to sell a deformed turtle. If the merchants call it a treasure turtle, the turnover will increase. Deformed turtles mean that some turtles are disabled at the moment they come out of their shells, such as no eyes, no tail and stunted limbs. The main reasons for these congenital disabled turtles are the instability of humidity and temperature during hatching, and the excessive vibration of turtle eggs, and the molded turtles will lose some organs during development due to these unfavorable factors.
