Polydora ciliata is a worm from the family of Spionidae within the class of polychaete (Polychaeta).

features

The yellowish brown or light yellow, at the end of the body darker ringworm reaches a body length of up to 30 mm and a width of 7 to 10 mm. The body consists of up to 180 segments. Dorsally, the species bears gills from the 7th segment , only the last 10 to 20 segments are without gills. The enlarged 5th segment has 6 to 7 particularly long, laterally toothed bristles. There are no or up to four eyes and two long palpi present, the average Occipital - antenna missing.

distribution

Polydora ciliata occurs in the entire North Sea , in the Skagerrak , Kattegat , Öresund , in the Baltic Sea , in the Indo-Pacific , from the Atlantic to the Mediterranean , in the Red Sea , in the Black Sea and in the Antarctic .

Way of life

Holes in the stone made by Polydora ciliata ; the big hole comes from a drill shell (dune in Helgoland)

Polydora ciliata: eggs (1), young larvae (2), older larvae (3–4), older stages (5–9), egg capsules (10). Lindsay G. Thompson (1893): History of the Fisheries of New South Wales

With the help of the bristles of the 5th segment, Polydora ciliata digs tubes in limestone, calcareous algae sediment ( Lithothamnia ) stones, clay soil or in old mussel shells. It also inhabits wood or laminaria adhesive organs. The worm can also be found in brackish water .

Taxonomy

Polydora ciliata was scientifically described for the first time in 1838 by George Johnston as Leucodore ciliatus in the Magazine of Zoology and Botany, Edinburgh .
