| From their studies of the hydroids at Georges Bank and in the lab, reported at several forums this fall, Sullivan and her colleagues are amassing evidence that the floating creatures (Clytia gracilis) are unrecognized, yet major players in the Georges Bank food web. These polar cells and the cell-to-cell junctions remind him of the stinging cells and junctions seen in jellyfish and hydroids -- both radially symmetrical invertebrates. Schmieder and others discovered that the rocky bank is smothered by a lush array of fluorescent strawberry anemones, yellow hydroids, pink tree-like hydrocorals, songes, algae and other sea life growing rampant atop one another. |
