A heavily damaged Flatworm swims near a coral reef. This flatworm speciman was so damaged, in many images you can actually see through a series of holes in the body. This is a common but unidentified Great Barrier Reef Flatworm (Pseudoceros sp.) found in remote northern Australia. This species is also regularly seen swimming from coral reef head to coral reef head in the undulating swimming motion often seen in marine flatworms.

Detached Reef's in this remote area are named as they are near - but not directly attached to the Great Barrier Reef system.
