The ornate worm is often found in marine environments also inhabited by Notomastus lobatus (Polychaeta) and Saccoglossus kowalewskyi (Hemichordata), which produce and contaminate sediments with bromophenols and bromopyrroles.
During a cave diving expedition to explore the Tunnel de la Atlantida, the world’s longest known submarine lava tube on Lanzarote in the Canary Islands, an international team of scientists and cave divers discovered the previously unknown species of crustacean, belonging to the remipede genus Speleonectes, along with two new species of annelid worms of the class Polychaeta.
