Terebellides

Terebellides is a genus of polychaete worms in the family Trichobranchidae. They were once considered to be cosmopolitan in their distribution, and were first examined in 1984 by Susan J. Williams. The specimens first examined were located in the Eastern Pacific. In recent years, there has been a shift of focus to study them in the Atlantic Ocean, due to their complex DNA. Relating to their geographic distribution emphasizes their differences in nephridia sizes this is the first and only characteristic found present in the Atlantic Ocean. This discovered the importance for relating further taxa to the study of them in the Atlantic Ocean compared to the eastern Pacific. Now, the current research on them is the discovery of their third region of the stomach and how it lacks an internal anatomical characteristic with the new introduction to further taxa.
