This site contains images of epizoic protozoans from the coast of California. A researcher
from the Marine Biology Laboratory of San Diego asks for help in specifying these species. If you can help, please

found on and remarks
|
I have seen this on two different species of Polychaeta. The ones pictured here were attached to the branchiae of
Ophelia pulchella (Opheliidae: Polychaeta) (Station: I3(2), 2JAN02, 92 ft.). They were also attached to the exterior
lateral body wall of the same specimen. A very similar looking animal (not pictured here) was found attached to the
branchiae and dorsal cirri of Mooreonuphis segmentispadix (B13(1), 1/9/02 375 ft.). In both cases the "ciliates"
occurred in the hundreds.
|
These animals were found attached to the palae (the thick brassy anterior setae that are directed forward) of
Amphicteis scaphopbranchiata (Ampharetidae: Polychaeta) (B10(1), 9JAN02, 381 ft.).
|
This one was to attached to the antennae of Mooreonuphis nebulosa (Onuphidae: Polychaeta) (2733(2), 17JUL01, 383 ft.).
