Huge clumps of Macrocystis integrifolia (Perennial Kelp) washed ashore with the tide. I haven't seen this beautiful kelp very often on our beaches.
This is the best example of Scytosiphon lomentaria (Soda Straws) I've ever found, healthy and still attached to a rock by its holdfast.
This frond of Pleurophycus gardneri (Broad-rib Kelp) was almost 2' long, and found on the beach at low tide. I don't see it very often.
A few young Nereocystis luetkeana (Bull Kelp) were growing, attached to rocks with holdfasts, among masses of young Alaria. The floats were about 1" diameter.
The Phaeophyceae or brown algae (singular: alga), is a large group of mostly marine multicellular algae, including many seaweeds of colder Northern Hemisphere waters. They play an important role in marine environments, both as food and for the habitats they form. For instance Macrocystis, a kelp of the order Laminariales, may reach 60 m in length, and forms prominent underwater forests. Another example is Sargassum, which creates unique habitats in the tropical waters of the Sargasso Sea....
