Figure 3.9. Algae of the tidal pools include the greens (Enteromorpha sp., and Rhizoclonium sp.; 

 upper left), blue-greens {Microcoleus lyngbyaceus and Schizothrix spp.) and diatoms (Gyrosigma 

 obliquum, Trachyneis aspera; lower right). These are fed upon by small molluscs (Assiminea and 

 Melampus; lower right). Adult flies (Ephydra, Ephydridae; upper right) and their larvae feed on 

 algae. The water boatman (Trichocohxia reticulata, left middle) can be dense in pools. The 

 California killifish (lower left) feeds on arthropods. Mclntire collection, © 1986 by Zedler.
