Deep water turtle recognizes its owner. Although turtles are cold-blooded animals, they will recognize their owners through smell and sound, and will slowly get used to their owners' presence through conditioned reflexes. Turtles are relatively timid and may feel scared when they first come into contact with their owners. However, as long as the owner is more patient, the tortoise will get closer to you. Usually after a turtle recognizes its owner, it can still interact with the owner at all times.

Performances of deep-water turtle recognition:

1. Open its mouth to receive food. If the owner feeds the turtle, it will approach the turtle actively, open its mouth, and wait for the turtle to feed. This also means that the turtle recognizes the owner.

2. Identify the owner. Turtles can also distinguish between their owners and strangers. Once a stranger comes to the home, the turtle will retract its head and become a turtle with a shrunken head. When there is only one owner at home, the tortoise will not be restrained and will explore everywhere with curiosity.

3. Will not run away. Speaking of the turtle's recognition of its owner, if it does not run away but approaches you when it is raised, this is also a sign of the turtle's recognition of its owner, and it may ask the owner for food.
