The crocodile turtle knows its master because its IQ is relatively long compared with other turtles, so after training, they can know their master. But when they first bought it, they didn't know the owner. Breeders need to train deliberately before they can know the owner accurately. After the small crocodile turtle knows its owner, its performance is obvious. If the owner approaches, they will take the initiative to swim over and stick out their heads, waiting for the owner to feed them. Before being domesticated, the small crocodile turtle's character is fierce, and after knowing its owner, its character will become relatively mild.

As mentioned above, the crocodile turtle can know the owner, but the breeder needs deliberate training before they can know the owner. It takes a lot of patience for them to know their owners. In the process of breeding at ordinary times, breeders need to feed themselves. If they have time, they can clamp the food with clips to interact with them. The time required for different species of crocodile turtles to recognize their owners is different, and some are faster, and they can be familiar with their owners in about a week. Some have poor adaptability, which takes about one month.

Although small snapping turtles can know their owners, their IQ is still limited, so it is best for breeders not to touch them directly, especially when they are hungry or irritable.
