Diopatra cuprea
species of annelid

Diopatra cuprea, commonly known as the plumed worm, decorator worm or sometimes ornate worm, is a species of polychaete worm in the family Onuphidae, first described by the French entomologist Louis Augustin Guillaume Bosc in 1802. It is native to the northwestern Atlantic Ocean, the Caribbean Sea and the Gulf of Mexico.
Description
Diopatra cuprea inhabits a parchment-like tube made of a mucous polysaccharide material, the tip of which projects from the sediment in which the rest of the tube is buried. The tube acts as a chimney; the lower part may be a metre long and is smooth with grains of sediment adhering to it. The upper part resembles an inverted "J", with the outer surface being reinforced with shell fragments and tiny pebbles which are cemented in the style of an overlapping mosaic. This part is extended by the worm if siltation threatens to bury it, and the tube occasionally has two entrances.
When these tubes are no longer occupied, they get washed out of the seabed and sometimes get deposited on the strand-line. The living worm is very colourful; its reddish-brown segmented body is iridescent, and often dotted with grey. Each segment bears a pair of yellowish-brown, oar-like parapodia with green speckles, which contrast with the bright red gills or "plumes" which endow the worm with its more common name, resembling a Christmas tree in rare cases. The occipital tentacles are covered with neat longitudinal rows of papillae of different sizes.

Why this record matters
“Diopatra cuprea” is worth following because a concise public description often conceals a longer documentary argument. Here, Diopatra, cuprea and species provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 20, 2026. The linked authority identifier is Q2854980. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1802.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
