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 tax

Rotularia is an extinct genus of planispirally coiled fossil polychaete worms in the family Serpulidae. Owing to the gastropod-like shape of Rotularia, many authors in the past interpreted this genus as being sea snails in the family Vermetidae. Like many other members from Vermetidae the Rotularia is approximately 5 inches in length. This is an estimate from the 151 confirmed fossil discoveries.

As of 2015, at least 12 species have been described, namely E. belizensis, E. bidentata, E centroamericana, E. cirripapillata, E. cryptica, E. erinaceus, E ettiennei, E. hartmannschroederae, E horrocksensis, E. kathrynae, E. opisthodentata, E. serratosetosa. The family contains two other genera, Sphaerosyllis (48 sp

Chaetopterus or the parchment worm or parchment tube worm is a genus of marine polychaete worm that lives in a tube it constructs in sediments or attaches to a rocky or coral reef substrate. The common name arises from the parchment-like appearance of the tubes that house these worms. Parchment tube worms are filter feeders and spend their adult lives in their tubes, unless the tube is damaged or destroyed. They are planktonic in their juvenile forms, as is typical for polychaete annelids. Species include the recently discovered deep water Chaetopterus pugaporcinus and the well-studied Chaetop

Sonatsa is a genus of marine, mud-dwelling polychaete worms containing the sole species Sonatsa meridionalis. S. meridionalis was described in 1919 by Ralph Vary Chamberlin from a single specimen collected by the research ship USS Albatross during a 1904–05 survey of the southeast Pacific Ocean. The type specimen was collected between Peru and the Galapagos Islands, from muddy sediment at a depth of around 4 km. The name Sonatsa derives from the Goshute words soma, meaning "many", and natsani, meaning "hook", while the specific name meridionalis is Latin for "southern".
