robofish take to the seas

                                                                       via inhabitat.

Soon, the water in Gijon, a harbor in Northern Spain will be monitored by robotic, battery-powered fish. These mechanical, articulating sea creatures were designed and tested by the Robotics Department at the University of Essex. At a cost of $3.6 million, through a European Union grant, these fish will test the water for oxygen levels, detect oil slicks and other contaminants pumped into the water. 

A great idea, though it may be far more effective if these were robosharks.
