[None. Introduction as:]
Orbiniidae are a taxon of sedentary annelids that vary in size from a few millimeters up to 50 cm. A total of 204 species are described, and most species can be found burrowing in sediment. Orbiniids are known from all marine habitats, including intertidal forms from sandy and rocky shores, as well as deep-sea forms. The deepest recorded orbiniid is Berkeleyia hadala, which has been found in abyssal depths in the Peru-Chile Trench in 6143 m (Blake 2017). The body is usually homonomously segmented and can bear up to some hundred chaetigers. Many of the large species are fragile and are only incompletely known. The by far best investigated species are members of the Scoloplos armiger species complex, which often are reported as highly abundant in ecological studies. The interstitial Questidae, questids have recently been transferred to Orbiniidae (Bleidorn et al. 2009). Since they superficially resemble clitellates in their reproductive biology and certain structures, they formerly have been discussed as being probably closely related to them (Almeida et al. 2003).
