Distribution of species between intertidal and subtidal zones. Bars indicate the numbers of species that had the specified percentage of their captures in the intertidal zone. stichaeids were Anoplarchus insignis (), Chiwlophis nugator and A. insignis (Arena Cove), and C. nugator (Diablo Cove), and the major scorpaenids were Sebastes caurinus (), S. flavidus, S. mystinus (Arena Cove), and S. mystinus and S. pinniger (Diablo Cove). Ronquils (Bathymasteridae) were abundant in and at Diablo Cove, but not at Arena Cove, and cusk eels and brotulas (Ophidiidae and Bythitidae) were collected in moderate numbers at Diablo Cove but not in the other two surveys. The general picture conveyed by the subtidal collections resembles that shown by the rocky intertidal fish faunas that occur along much of this same geographical range (Yoshiyama et al. 1986). There was overall similarity between the surveyed areas in the major groups of fishes present (, cottids, stichaeids, scorpaenids), but there was a definite latitudinal change in species composition of the fauna. Within each of the three surveys, species abundances generally were different between shoreline and deeper subtidal collections (Table 1). At Diablo Cove, the shoreline (including intertidal) collections were dominated by the eel blennies Xiphister atropurpureus, X. mucosus, and Xererpes fucorum, while these species were rare or absent in the subtidal collections. Conversely, the bothid flatfish Citharichthys stigmaeus and the hexagrammid Oxylebius pictus were much more abundant in the subtidal areas than shoreward. Most of the other species also were concentrated in either the shoreline or deeper subtidal areas. The same was true for
