I've been out of town, but returned to find a query about Hyalinoecia. I
dissected about 50 specimens of Hyalinoecia artifex for my dissertation
and concluded that they were predators. More than 40 of them had empty
guts, but those 6 that were not empty had ingested amphipods (tubes and
all), isopods, benthic copepods, and some forams. Photographs taken in
tandem with my samples showed the bottom littered with Hyalinoecia artifex;
apparently they were grazing over the bottom, all facing the same direction.
I published the results in:
Gaston, G.R. 1987. Benthic Polychaeta of the Middle Atlantic Bight:
feeding and distribution. Marine Ecology-Progress Series 36: 251-262.
My dissertation citation is:
Gaston, G.R. 1983. Benthic Polychaeta of the Middle Atlantic Bight:
feeding and distribution. Ph.D. Dissertation. College of William and
Mary. Williamsburg, Virginia.
(available through the VIMS library at Gloucester Point, Virginia as well).
Glad to help,
Gary
