Terebellida

species of annelid

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 (e.g. the Saccocirridae), 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 (deposit feeders) which live in small tubes they build from mud or similar substrate, or burrow in the sand. Their central nervous system displays characteristic apomorp

Pectinariidae, or the trumpet worms or ice cream cone worms, are a family of marine polychaete worms that build tubes using grains of sand roughly resembling ice cream cones or trumpets. These structures can be up to long. The earliest pectinariid fossils are known from the Cretaceous.

The Terebellidae is a marine family of polychaete worms, of which the type taxon is Terebella, described by Carl Linnaeus in his 1767 12th edition of Systema Naturae.

The Alvinellidae are a family of small, deep-sea polychaete worms endemic to hydrothermal vents in the Pacific Ocean. Belonging to the order Terebellida, the family contains two genera, Alvinella and Paralvinella; the former genus contains two valid species and the latter eight. Members of the family are termed alvinellids.

Ampharetidae are a family of terebellid "bristle worm" (class Polychaeta). As such, they belong to the order Canalipalpata, one of the three main clades of polychaetes. They appear to be most closely related to the peculiar alvinellids (Alvinellidae) which inhabit the deep sea, and somewhat less closely to the well-known trumpet worms (Pectinariidae). These three appear to form one of the main clades of terebellids.

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.

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 (able to be turned inside-out) head. Unlike many polychaetes, they also have large, pigmented, complex eyes.

species of marine worm

Acrocirridae is a family of polychaete worms. Acrocirrids are detritivores (deposit feeders), catching falling particles with numerous long prostomial tentacles. There are eight known genera, and at least 21 described species and subspecies within the Acrocirridae. The acrocirrids are primarily benthic (seabed-dwelling) animals, but at least two genera (Swima and Teuthidodrilus) appear to have evolved or adapted to a pelagic (free-swimming) habitat.

Poeobius is a genus of marine polychaete worm. It contains the single species Poeobius meseres, or balloon worm. This is a common and abundant resident in the midwater around the mesopelagic and bathypelagic zones, especially in Monterey Bay. They can be found at around 300-2,500 m (980-8,200 ft) depth from Japan to Alaska to the Gulf of California, and have also been reported in South America.

Dodecaceria is a genus of marine polychaete worms in the family Cirratulidae. It's also one of the very few polychaete genera with a verified fossil record.

Lanice, (also known as the sand mason worm), is a genus of burrowing marine polychaetes (commonly referred to as "bristle worms") typically found in the littoral zone.

Terebellides is a genus of polychaete worms in the family Trichobranchidae. They were once considered to be cosmopolitan in their distribution, and were first examined in 1984 by Susan J. Williams. The specimens first examined were located in the Eastern Pacific. In recent years, there has been a shift of focus to study them in the Atlantic Ocean, due to their complex DNA. Relating to their geographic distribution emphasizes their differences in nephridia sizes this is the first and only characteristic found present in the Atlantic Ocean. This discovered the importance for relating further tax

Biremis blandi is a species of marine polychaete worm and the only species in the genus Biremis. It was first described by Polloni, Rowe, and Teal in 1973. The species was discovered in 1971 during a dive by the research submersible DSV Alvin at in the Tongue of the Ocean in the Bahamas. It is named for Alvin pilot Edward L. Bland, Jr., who first observed it.
