Description edit

Members of this genus live in thick, parchment-like tubes that project from the sediment on the seabed. The tubes are covered on the outside by fragments of shell, algae, fibers and other small objects, collected by the worm and stuck in place by mucus. The worm's tube is a food-catching tool that creates a small micro-reef where small invertebrate prey reside. Diopatra dart partially out of the tube and grasp the prey with their maxillae and mandibles. Their large anterior parapodia help them to immobilize the prey.[2]

Species edit

The World Register of Marine Species includes these species in the genus.[1] A 2021 study also identified 4 new species in the south-west Atlantic.[3]
