Spionidae
Spionidae is a family of marine worms within the Polychaeta. Spionids are selective deposit feeders that use their two grooved palps Pedipalps (commonly shortened to palps or palpi) are the second pair of appendages of chelicerates – a group of arthropods including spiders, scorpions, horseshoe crabs, and sea spiders. The pedipalps are lateral to the chelicerae ("jaws") a ... to locate prey. However, some spionids are capable of interface feeding, i.e. switching between deposit and suspension feeding. Spionids produce tubes by cementing sand grains and detritus material with mucus produced by their glandular pouches. The Spionidae is one of the most studied polychaete families given their biological and commercial importance. Members of this family have been used in regeneration studies and some are capable of boring into calcareous substrate which has destructive implications for commercially important shellfish.

Scolelepis Squamata
''Scolelepis squamata'' is a species of polychaete worm in the family Spionidae. It occurs on the lower shore of coasts on either side of the Atlantic Ocean. Description ''Scolelepis squamata'' is a slender, bluish-green worm with a maximum length of about and over two hundred segments when fully grown. The prostomium (head) is diamond-shaped and has four eyes, arranged in a trapezoid fashion, two long slender palps, and no central antenna. Each segment has a pair of parapodia with chaeta (bristles). The dorsal lobes of the parapodia are long and thin and are fused to the gills for half their length. The ventral lobes are rounded and short, and slightly bilobed from segment 20 onwards. There are gills (red) on all segments except segment 2 and the last seven body segments. Distribution and habitat ''Scolelepis squamata'' is found on both sides of the Atlantic Ocean, the Mediterranean Sea, the Caribbean Sea and the Gulf of Mexico. It digs a burrow in the sediment in the lower par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polydora (polychaete)
''Polydora'' is a genus of annelid worms. It contains marine polychaete species that live in mud, holes bored in rocks, and holes bored in the shells of shellfish. Some shell- and rock-boring polydora worms leave a characteristic double hole in the rock and shells in which they burrow. Etymology From the Ancient Greek Πολυδωρη, from Polydora, daughter of Tethys and Ocean in Greek mythology. Economic effects Polydora species are a major economic issue for parts of the shellfish industry. Some species cause "mudblister" on oysters, living inside the oyster shell and roughening its interior surface. Although this makes the oyster grow much more slowly, and makes the shell ugly and harder to sell, the meat of the oyster is still fit to eat.
