Olive, golden or yellow-brown

Bleached foliose red algae

* Indicator Species: The dominant species in a bioband and usually what the bioband is named for (eg. Barnacles = Barnacle bioband or BAR).
  Associated Species: Species commonly found within a given bioband. These are based on known life histories of these species and ground observations. For more detailed information on associated species and regional differences see the Shore Station database (http://alaskafisheries.noaa.gov/habitat/shorestation/default.htm).
