In reply to the discution of the worldwide distribution of some
polychaete species. I found a article titled "Ecological Roulette: The
Global Transport of nonindigenous marine organisms" Science, 261: 78-82
(1993). Cartlon and Geller sampled ballast water from 159 cargo ships in
Coos Bay, Oregon, USA. The ships and their ballast water were originated
from 25 Japanese Ports. They found a minimum of 367 different marine taxa,
including spionids, polynoids among other polychaete families.
These study may explain the transpacific distribution in the recent past.
The interesting point is, how many transpacific species Jim Blake found in
