'SharkCam' films basking sharks off Scotland

A 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. SharkCam followed three sharks off the coasts of Coll and Tiree. The robot monitored the animals from a distance and recorded behaviour that suggested they arrive in Scottish waters to breed rather than feed.
