Shanghai customs says they seized more than 2,000 endangered turtles last November.
Customs officials discovered large numbers of live turtles hidden in six containers of crabs imported from Indonesia last November. The containers were claimed by a Shanghai company.
Most of the turtles were endangered species including Amboina box turtle, pig-nosed turtle and spotted pond turtle.
The turtles are now in the care of local zoos.
The investigation is still underway.
