'SharkCam' films basking sharks off Scotland Published duration 28 Augustimage copyright WHOI image caption The sharks were observed swimming just above the seabedA robot camera has been used in UK seas for the first time to monitor the behaviour of basking sharks. SharkCam was deployed off the west coast of Scotland where the sharks gather to breed after migrating from waters off west Africa. Basking sharks, an endangered species, are the world's second largest fish after whale sharks, sometimes growing to more than 10m (33ft) long. But studying the footage gathered last summer by SharkCam, scientists noted the sharks spent long periods just above the seabed and were not feeding. image copyright WHOI image caption A basking shark close to the surface with its mouth open in feeding behaviourNatureScot, formerly Scottish Natural Heritage, worked on the project with Woods Hole Oceanographic Institution, WWF/Sky Ocean Rescue and the University of Exeter.
