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.
Wrinkled and constricted at the base, not smooth like Sea Sacs. Small sacs, with smaller specimens showing more wrinkling.
