Title: Predation on the chiton Cyanoplax hartwegii (Mollusca: Polyplacophora)
Student Author(s): DeBevoise, Anne E.
Pages: 13
Location: Final Papers Biology 175H
Date: June 1974
Keywords: chiton
Abstract: According to both the experiments and field observations, potential predators on Cyanoplax hartwegii are ranked as follows: Leptasterias pusilla (on chitons 1 cm), Pisaster ochraceus >>> Pachygrapsus crassipes (occasional), Hemigrapsus nudus (occasional). The algal covering of Pelvetia fastigiata is a protective barrier from predation against Pisaster ochraceus, and possibly from birds; all the other potential predators tested showed no preference for chitons on bare rocks as opposed to those covered by Pelvetia.
