None. Begins: "Sabellariidae Johnston, 1865, is a well-defined and highly specialized group of marine annelids commonly known as honeycomb or sandcastle worms. They live in characteristic tubes of cemented sand grains, other mineral or biogenic particles such as Foraminifera (Kirtley 1994), sometimes attached to one another forming large reefs that can extend over several kilometers. They cannot survive out of their tubes and are unable to build new ones if removed from them. Sabellariids have a well-developed operculum with rows of golden paleae that can seal the entrance of the tube when the animal withdraws into it (Figs. 7.4.5.1 A, B and 7.4.5.2 A, C). Both structures, tube and operculum, provide protection from desiccation, silt deposition, and predators. The monophyly of Sabellariidae has been assessed, and relies on synapomorphies such as the presence of an operculum formed by the head and two anterior segments, a pair of peristomial palps, nuchal organs located at the base of palps, a building organ, oral filaments originating from segment 1 (not the peristomium), paleae on the anterior segments, uncini without a rostrum or main fang and without a handle or manubrium, segmental branchiae inserted dorsally on the parapodia and an expansion of the gut in the abdomen called the “proventriculus” (Capa et al. 2012, Hutchings et al. 2012, Helm et al. 2018a).
