The US military has revealed plans to use fish as ‘underwater spies’ to monitor enemy activity, as part of the Persistent Aquatic Living Sensors (PALS) project. Speaking at the launch of the project, Dr Lori Adornato, programme manager, said: “The US Navy’s current approach to detecting and monitoring underwater vehicles is hardware-centric and resource intensive. “As a result, the capability is mostly used at the tactical level to protect high-value assets like aircraft carriers, and less so at the broader strategic level. According to Scientific American , one team is focusing on goliath groupers - fish they believe could be used to detect approaching submarines or drones. The results from the five teams are expected to be published in the next few years, after which the US military will decide how to use fish going forwards.
