Shanghai customs said Sunday they seized more than 2,000 endangered turtles last November in what could be the city's largest turtle smuggling case.
Customs officials said they discovered large numbers of live turtles hidden in six containers of crabs imported from Indonesia on Nov. 19. 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, officials said.
The customs did not give more details, saying the investigation was still underway.
Environmentalists have warned China's rising market for rare and exotic pets, such as turtles and snakes, has fueled smuggling.
