A large sea snail, two kinds of clam and a marine worm were found during Marine Scotland surveys around the Rockall plateau in the north Atlantic.
The creatures had previously avoided detection despite decades of research in the area, which is located hundreds of miles off the north-west coast.
This picture shows the head of an antonbrunnia, or marine worm, which was one of the species found during the surveys. It has yet to be formally named, and is currently being examined at the National Museum of Wales. It's the first of its kind to be found in the Atlantic.
