Some smart soft-shelled turtles or those who have been raised for a long time will appear very human and will know their owners. The premise is that you have to raise them well, if you raise them well, you go to play with them more, don't abuse them, and let them get to know you as they grow up.

For example, when feeding, put the food in front of it and let it grab it , after a long time, they may know you, at least when they see you, they will know that they are going to eat.
