Sperm whales, the world's largest toothed whale, have been sighted sleeping on the surface in the waters off the Isle of Lewis in Scotland.
Steve Dodd, a local volunteer observer for the Whale and Dolphin Conservation Shorewatch programme, made the sighting, and reported that the 12 large sperm whales were ‘logging' – the term used to describe sleeping whales and dolphins – for more than an hour off Tiumpan on Wednesday.
The huge mammals, which can grow to more than 18 metres long, are a rare sight off the Scottish coastline, normally only being encountered during a stranding event.
