Sabellidae
Encyclopedia
Sabellidae are sedentary marine polychaete
tube worms where the head is mostly concealed by feathery branchiae. They build tubes out of parchment, sand, and bits of shell. They tend to be common in the intertidal zones around the world.

Feather-duster worms have a crown of feeding appendages or radiole
s in two fan-shaped clusters projecting from their tubes when under water. Each radiole has paired side branches making a two-edged comb for filter feeding. Most species have a narrow collar below the head. The body segments are smooth and lack parapodia
. The usually eight thoracic segments bear capilliaries dorsally and hooked chaeta
e (bristles) ventrally. The abdominal segments are similar but with the position of the capilliaries and chaetae reversed. The posterior few abdominal segments may form a spoon-shaped hollow on the ventral side. Size varies between tiny and over ten centimetres long. Some small species can bend over and extend their tentacles to the sea floor to collect detritus.

The following genera belong to the family :
Polychaete
The Polychaeta or polychaetes are a class of annelid worms, generally marine. Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. Indeed, polychaetes are sometimes referred to as bristle worms. More than 10,000...

Chaeta
A chaeta or cheta is a chitinous bristle or seta found on an insect, arthropod or annelid worms such as the earthworm, although the term is also frequently used to describe similar structures in other invertebrates. The plural form is chaetae or chetae.In the Polychaeta, they are located on the...
