“…The worms are tubicolous, building vertical tubes in the sediment that may extend their upper portion (known as the tube-cap) a few centimetres above the sediment (Figure 6). Their tubes vary from having scarcely any ornamentation, being mostly composed of silt and fine sand (Figure 6C), to being exquisitely ornamented with shells, seaweed, or any foreign material (Figure 6A,B), and often serve as good field characters as to species [11,[50][51][52][53][54][55]. Almost unique to Diopatra is that materials such as shells are attached edge-on, imbricately, rather than flat, as in most tube-builder constructions.…”

The annelid genus Diopatra occurs in all major oceans but is best represented in the shallow depths of warmer waters, where it lives in elaborately decorated tubes. This paper provides an introduction to the animals, discussing their history and diversity. We describe and illustrate its morphology and geographic distribution. While they were thought to be predominantly gonochoristic, recent reproductive studies show that several species are protandric simultaneous hermaphrodites. Development is by broadcast spawning with a brief pelagic stage or direct development in the parental tube or egg mass attached to it. Diopatra is a key ecosystem engineer, altering water flow and deposition and increasing the availability of refugia. We also discuss its harvesting as fishing bait, its role as an alien or introduced species, its capacity to regenerate, its therapeutic potential, and its applications as a bioindicator species for climate change, geographic distribution changes, and dispersal.
