A self-controlled swimming robot has completed a journey from San Francisco to Australia.
The record-breaking 9,000 nautical mile (16,668km) trip took the PacX Wave Glider just over a year to achieve.
Liquid Robotics, the US company behind the project, collected data about the Pacific Ocean's temperature, salinity and ecosystem from the drone.
The company said its success demonstrated that such technology could "survive the high seas".
