Marine Worm
A close-up view shows the mouth of a yellow marine worm, one of some 8,000 species of polychaetes, named for the many bristles that typically cover their bodies. Polychaetes are holdovers from a far more ancient Earth. They appear in the fossil record at least as early as the Cambrian period, 540 to 490 million years ago.
