Polychaeta (/ ˌ p ɒ l ɪ ˈ k iː t ə /) is a paraphyletic [1] class of generally marine annelid worms, commonly called bristle worms or polychaetes (/ ˈ p ɒ l ɪ ˌ k iː t s /). 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 ...
Sirsoe methanicola is a species of polychaete worm that inhabits methane clathrate deposits in the ocean floor. The worms colonize the methane ice and appear to survive by gleaning bacteria, which in turn metabolize the clathrate. In 1997, Charles Fisher, professor of biology at Pennsylvania State University, discovered the worm living on ...
The gossamer worm (Tomopteris, Neo-Latin from Greek meaning "a cut" + "wing" but taken to mean "fin") [3] 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.
Alvinella pompejana, the Pompeii worm, is a species of deep-sea polychaete worm (commonly referred to as "bristle worms"). It is an extremophile found only at hydrothermal vents in the Pacific Ocean , discovered in the early 1980s off the Galápagos Islands by French marine biologists .
Juvenile and other worms of small size have small crowns and radioles, so prefer to capture and eat very small particles, such as bacterioplankton and single-celled phytoplankton and zooplankton. As a worm matures and grows in size, so does its crown. The larger crown allows the animal to feed on larger multicellular plankton.
Lanice conchilega, commonly known as the sand mason worm, is a species of burrowing marine polychaete worm. It builds a characteristic tube which projects from the seabed, consisting of cemented sand grains and shell fragments with a fringe at the top. Polychaetes, or marine bristle worms, have elongated bodies divided into many segments.
With 28 different species of fireworms and thousands of species of polychaetes in the ocean among other things, it should come as no surprise that Tunnell tells people to avoid touching stuff.
The genus Glycera is a group of polychaetes (bristle worms) commonly known as bloodworms.They are typically found on the bottom of shallow marine waters, and some species (e.g. common bloodworms) can grow up to 35 cm (14 in) in length.
