Polychaetes and the worm-shaped animals from several other phyla. Most of them are known by the part that shows.
A spaghetti worm is a mat of white feeding tentacles on the sand with the animal out of sight below it; the feather duster and Christmas tree worms are crowns that withdraw before a shutter can fire; the acorn worm is the source of many of the coiled sand casts on a silt slope. The peanut worm, the spoon worm and the ribbon worm are each a different phylum and are grouped here by shape alone.
Two are worth keeping clear of. The bristle worm's brittle white bristles break off in skin at the lightest contact, and the bobbit worm, a large predatory eunicid, strikes from a burrow and is best watched at night. The bearded fireworm is the Atlantic equivalent of the first and is handled the same way, which is not at all.
Every one has a page. They are shown as a list rather than as pictures because nothing has been photographed or logged for them yet, and a species with nothing behind it should not sit in front of one that has.
How many of the 11 carry a record at each destination. A species usually carries several, so these do not add up to 11.
