Biologists opening clams collected at a Blake Ridge cold seep, int he deep sea off the coast of South Carolina, USA, in 2001 discovered that nearly every clam was occupied by one or more tiny, segmented worms. The worms in the clams belong to a group known as the nautiliniellids and the collected specimens were unlike any other described species.
