Dodecaceria is a genus of marine polychaete worms in the family Cirratulidae. [1] It's also one of the very few polychaete genera with a verified fossil record.
The genus contains bioluminescent species. [2]

The earliest species on record, Dodecaceria cretacea (Voigt, 1971), later reclassified as the ichnofossil Caulostrepsis cretacea, was responsible for leaving boring traces on Late Cretaceous coral reefs. [3] Authors such as Fischer et al. (1989 [4] , 2000 [5] ) have proposed that Diplochaetetes fossil bioconstructions may be attributed to Dodecaceria due to synonymity. A research by Guido et al. (2024) [6] reported very similar double-phased biomineralization processes in bioconstructions attributed to these genera.
The following species are recognised in the genus Dodecaceria: [1]
Polychaeta is a paraphyletic class of generally marine annelid worms, commonly called bristle worms or polychaetes. Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. More than 10,000 species are described in this class. Common representatives include the lugworm and the sandworm or clam worm Alitta.
The gossamer worm is a genus of marine planktonic polychaetes. All described species are known to be holoplanktic, meaning that they spend their entire life cycles in the water column.
Eunicidae is a family of marine polychaetes. The family comprises marine annelids distributed in diverse benthic habitats across Oceania, Europe, South America, North America, Asia and Africa. The Eunicid anatomy typically consists of a pair of appendages near the mouth (mandibles) and complex sets of muscular structures on the head (maxillae) in an eversible pharynx. One of the most conspicuous of the eunicids is the giant, dark-purple, iridescent "Bobbit worm", a bristle worm found at low tide under boulders on southern Australian shores. Its robust, muscular body can be as long as 2 m. Eunicidae jaws are known from as far back as Ordovician sediments. Cultural tradition surrounds Palola worm reproductive cycles in the South Pacific Islands. Eunicidae are economically valuable as bait in both recreational and commercial fishing. Commercial bait-farming of Eunicidae can have adverse ecological impacts. Bait-farming can deplete worm and associated fauna population numbers, damage local intertidal environments and introduce alien species to local aquatic ecosystems.
The Serpulidae are a family of sessile, tube-building annelid worms in the class Polychaeta. The members of this family differ from other sabellid tube worms in that they have a specialized operculum that blocks the entrance of their tubes when they withdraw into the tubes. In addition, serpulids secrete tubes of calcium carbonate. Serpulids are the most important biomineralizers among annelids. About 300 species in the family Serpulidae are known, all but one of which live in saline waters. The earliest serpulids are known from the Permian.
Harmothoe is a genus of marine Polychaete worms belonging to the family Polynoidae. Species of Harmothoe are found world-wide to depths of at least 5,000 m but are more common in shallower water.
Terebellida make up an order of the Polychaeta class, commonly referred to as "bristle worms". Together with the Sabellida, the Spionida and some enigmatic families of unclear taxonomic relationship, they make up the subclass Canalipalpata, one of the three main clades of polychaetes. Like most polychaetes, almost all members of the Terebellida are marine organisms. Most are small, sessile detritivores which live in small tubes they build from mud or similar substrate, or burrow in the sand. Their central nervous system displays characteristic apomorphies.
Hesionidae are a family of phyllodocid "bristle worms". They are marine organisms. Most are found on the continental shelf; Hesiocaeca methanicola is found on methane ice, where it feeds on bacterial biofilms.
Chaetopterus or the parchment worm or parchment tube worm is a genus of marine polychaete worm that lives in a tube it constructs in sediments or attaches to a rocky or coral reef substrate. The common name arises from the parchment-like appearance of the tubes that house these worms. Parchment tube worms are filter feeders and spend their adult lives in their tubes, unless the tube is damaged or destroyed. They are planktonic in their juvenile forms, as is typical for polychaete annelids. Species include the recently discovered deep water Chaetopterus pugaporcinus and the well-studied Chaetopterus variopedatus.
Phyllodoce is a genus of polychaete worms, which contains about 200 species. The prostomium bears eyes, two pairs of antennae and a pair of large retractile nuchal organs. The eversible proboscis is clearly divided into two parts.
Cirratulidae is a family of marine polychaete worms. Members of the family are found worldwide, mostly living in mud or rock crevices. Most are deposit feeders, but some graze on algae or are suspension feeders. Although subject to multiple revisions over time, cirratulids are among the few polychaete clades with a verified fossil record.
Orbiniidae is a family of polychaete worms. Orbiniids are mostly unselective deposit feeders on marine detritus. They can be found from the neritic zone to abyssal depths.
Sabellaria is a genus of marine polychaete worms in the family Sabellariidae. The type species is Sabellaria alveolata. These worms are sedentary and build tubes in which to live from sand and shell fragments. Some species are called honeycomb worms and when they occur in great numbers they can form reefs on rocks and other hard substrates. They are filter feeders, extending a plume-like fan of radioles from the end of the tube in order to catch plankton and detritus floating past. They have a distinctive operculum which is used to block the opening of the tube when the radioles are retracted.
Cirriformia is a genus of marine polychaete worms in the family Cirratulidae.
Phyllodocidae is a family of polychaete worms. Worms in this family live on the seabed and may burrow under the sediment.
Eulalia is a genus of polychaete worms.
Lepidasthenia is a genus of marine Polychaete worms belonging to the family Polynoidae. Species of Lepidasthenia are found worldwide to depths of about 1200 m but are more common in shallower water.
Eunice aphroditois is a benthic bristle worm of warm marine waters. It lives mainly in the Atlantic Ocean, but can also be found in the Indo-Pacific. It ranges in length from less than 10 cm (4 in) to 3 m (10 ft). Its exoskeleton displays a wide range of colors, from black to purple and more. This species is an ambush predator; it hunts by burrowing its whole body in soft sediment on the ocean floor and waiting until its antennae detect prey. It then strikes with its sharp mouthparts. It may also be found among coral reefs.
Flabelligeridae is a family of polychaete worms, known as bristle-cage worms, notable for their cephalic cage: long slender chaetae forming a fan-like arrangement surrounding the eversible head. Unlike many polychaetes, they also have large, pigmented, complex eyes.
Dipolydora is a genus of polychaetes belonging to the family Spionidae.
Buskiella is a genus of pelagic polychaete annelids placed either in the family Flotidae or Flabelligeridae. In appearance, they are generally bluish or yellowish, depending on lighting conditions, and live exclusively in very deep water. They move by swinging their bodies from side to side, "rowing with [their] bristles." Species have nine to eleven chaetigers.
