[Cnidaria] unidentified anenome-like parasites on jellyfish and an anemone hitching a ride

[jdpierce tds.net]

Looks like Peachia.  I believe P. hilli is a local one for you, found on
Catostylus (see Badham, 1917).   Here are a couple refs. to get you started.


Badham, C.  1917.  On a larval actinian parasitic in a rhizostome.  Quarterly
Journal of Microscopical Science.  62: 221-229.


McDermott, J. J., P. L. Zubkoff, and A. L. Lin. 1982. The ocurrence of the
anemone *Peachia parasitica* as a symbiont in the scyphozoan *Cyanea
capillata* in the lower Chesapeake Bay. Estuaries 5:319–321.

Spaulding, J. G. 1972. The life cycle of *Peachia quinquecapitata*, an
anemone parasitic on medusae during its larval development. Biological
Bulletin 143:440–453.
