Giant leatherback turtles know their owners. If the owner feeds the giant leatherback turtle and finds that the giant leatherback will quickly paddle its limbs, approach itself, and then open its mouth, waiting for it to feed, it means that the turtle recognizes the owner.

Giant leatherback turtles can also distinguish between owners and strangers, once home When strangers come, giant leatherback turtles tuck their heads in. When there is only one owner at home, the giant leatherback will not be restrained, and the giant leatherback will explore everywhere with curiosity.
