Ryan Photographic - Sabellidae - Feather duster worms
Family Sabellidae
The family Sabellidae contains 1177 species in 76 genera (not trombones). Their common name of feather duster worms relates to their feathery gills which are also used for feeding. Most sabellids secrete a papery tube which is mixed with sand grains. When threatened they quickly withdraw into them. Most possess eyespots which are excellent at detecting movement and in some they might be able to form images (this is supposition on my part btw). Ragged edges to the gills of some suggest that occasionally they aren't quite quick enough.
Sabellids are found in all the world's oceans, typically in shallow waters but some live in the deep sea.
Other common names include peacock worms and fan worms.
Many of the animals in the photos below are identified only to family or genus. These worms are difficult to identify without specimens. Any identifications would be welcome.
