Dear Elianne,
There was a similar question some years ago in ANNELIDA mailing list,
by Brigitte Hilbig (04Jun99), and an answer by Mike Vecchione
(07Jun99).
See the ANNELIDA archives for both the question:
http://www.bio.net/hypermail/annelida/annelida.199906/0005.html
and the answer:
http://www.bio.net/hypermail/annelida/annelida.199906/0008.html
Probably Brigitte Hilbig can tell you more about it.
There is also an old paper by Stewart (1881) on a Eunicidae supposed to have
some boring activity on a telegraphic cable off Singapore. The eunicid in
question was described as Lithognatha worslei, new species new genus, and
later considered to be an undeterminable Palolo by Kristian Fauchald (1992:
1210).
Of course, there is the possibility that the eunicids are only squatters of
the somebody else's holes (see the above messages on the ANNELIDA archives).
I hope this can help.
Best wishes,
João Gil
