China's Ministry of State Security alleges foreign agencies are waging an "unseen covert war" by using "spy turtles" and "spy fish" with sensors to collect maritime data. The ministry claims the goal is to create underwater maps and find coastal defense weaknesses. Beijing is offering rewards up to 500,000 yuan for citizens who report spy devices, amid historical parallels of Russia using dolphins for military purposes.
