On its surface, Loch Carron is a beautiful, tranquil highland sea loch on the northwest coast of Scotland. The highlands there are home to a diverse range of wildlife, including pine martens, red deer, and oystercatchers. Hidden deep below the loch’s surface is an equally beautiful haven for starfish, flame shells, and beds of maerl, a species of coral-like red algae.
