Flame shells are seen on the sea bed near Skye, in this undated handout photograph received in London on December 27, 2012. The colony, which was uncovered during a survey commissioned by Marine Scotland, consists of at least 100 million flame shells, and is located in Loch Alsh, which is a sea inlet between Skye and the coast of the mainland on the west of Scotland, local media reported.
