Collected during squid collecting trip at surface. Hosted a Sargassum nudibranch.
Sorry no holdfast attached.
Lacy, fine, nearly translucent light brown algae (or possibly seaweed) growing profusely on dock. Clumps 6-12" but hard to tell where one ends and he next one starts because it was so fragile.
All along the understory walk/Cataract Trail
ID as per http://www.beachwatchers.wsu.edu/ezidweb/seaweeds/Pterygophera.htm (Note - they have a typo in the genus name and thus URL!)
The Chromista are a eukaryotic supergroup, probably polyphyletic, which may be treated as a separate kingdom or included among the Protista. They include all algae whose chloroplasts contain chlorophylls a and c, as well as various colorless forms that are closely related to them. These are surrounded by four membranes, and are believed to have been acquired from some red algae.
