This is the moment a hungry pet turtle chased a small crab on the floor.

Footage captured by Mr Wang shows the big-headed turtle crawling out of its water-filled plastic box after spotting the crustacean wandering nearby in Guangxi, China.

The ravenous reptile charged with surprising speed toward the shellfish trying to skitter away on May 20.

However, the turtle managed to corner its prey, clamping down on its legs before dragging it away into a corner of the room.

The turtle was heard feasting on the snack with a loud crunch.

Big-headed turtles are omnivorous reptiles native to Southeast Asia. Their diet typically includes aquatic invertebrates, small fish, amphibians, and crustaceans. Known for their powerful jaws, these turtles are capable predators in both wild and captive environments.
