China Accuses Foreign Agencies of Deploying “Spy” Turtles, Fish and Other Underwater Devices

Alleged Underwater Espionage: Spy Turtles and Spy Fish
China’s Ministry of State Security (MSS) posted on the WeChat platform that foreign intelligence services are fitting marine animals with sensors to collect “sensitive marine environment data such as water temperature, salinity and ocean currents in real time” and transmit the information overseas via satellite. The ministry described the activity as an “invisible secret war” and an “unseen covert war of espionage” unfolding in the seas surrounding China’s coast.
Historical Precedents of Marine-Animal Surveillance
The claim echoes earlier reports of animal-based espionage. In 2019 a beluga whale equipped with a camera harness was found off Norway, sparking speculation about Russian use. British intelligence in 2023 said Russia was training bottlenose dolphins at its Sevastopol Black Sea fleet base to counter enemy divers. China itself has previously reported buoys deployed by an overseas marine-research institute and underwater “lighthouses” on the seabed that could guide foreign submarines.
Data, Devices, and Financial Incentives
The MSS listed several categories of equipment: sensor-fitted turtles and fish, detection buoys, a solar-powered “wave glider” that moves with ocean currents, and ship-borne electronic systems. Collected data allegedly includes acoustic signatures of Chinese submarines, naval vessel movements, and seabed topography. To encourage civilian reporting, Chinese authorities have offered fishermen cash rewards ranging from 50,000 to 500,000 yuan (? $7,300–$73,000) for turning in suspected spying devices.
Official Chinese Government Statements
- The MSS warned that foreign actors are continuously gathering maritime data through “various new types of espionage equipment.”
- It urged researchers, fishermen and vessel owners to remain vigilant and report suspicious devices.
- China’s foreign ministry announced the detention of a U.S. citizen on espionage charges and barred Philippine Defence Secretary Gilberto Teodoro from entering China, citing “erroneous remarks” that undermine Chinese interests.
Criticism and Calls for Evidence
Analysts cited by The Guardian note that the MSS provided no details on where the animals were found or which nations were responsible, making independent verification impossible. Observers also point out that similar past claims have lacked corroborating evidence, raising questions about the plausibility of large-scale animal-based surveillance in heavily contested waters such as the South China Sea, East China Sea and Taiwan Strait.
Conflicting Reports and Information Gaps
- No specific locations or species of the alleged “spy” turtles and fish have been disclosed.
- The identities of the foreign intelligence services remain unnamed.
- Separate reports of Japanese surveillance aircraft near Taiwan were mentioned, but no direct link to the marine-animal allegations was established.

Outlook and Potential Developments
China is expected to maintain heightened maritime patrols and continue its reward program for civilian tips. The detention of foreign nationals and diplomatic sanctions suggest a broader security posture that may extend to further investigations of alleged underwater spying. As regional tensions persist, especially with the Philippines and Japan, Chinese authorities are likely to emphasize vigilance against perceived foreign surveillance in the contested maritime zones.
