Here are three photos of a seaweed I've never seen before, possibly Nemalion helminthoides or Rubber Threads. There were a few clumps growing in shallow water during the -2.1 minus tide where brackish water drains into Oak Bay. The strands measured to 3' long, and they felt supple like wet noodles. Unlike the photo in Andy Lamb's book, these algae did show some branching.
These two photos show one of the most beautiful of the red seaweeds, Microcladia coulteri or Delicate Sea Lace. This clump measured about 10" across.
Since I was using my macro lens, it was fun to photograph Chondracanthus exasperatus or Turkish Towel up close!
I found this red seaweed called Microcladia borealis or Coarse Sea Lace at low tide on the beach. It measures about 6" across, and was very supple.
I found this red seaweed on the beach at low tide and believe it is Chondracanthus corymbiferus, about 3' across the clump of fronds. However these fronds were ruffled more than Chondracanthus exasperatus aka Turkish Towel, and the texture wasn't as rough.
The red algae, or Rhodophyta (/roʊˈdɒfɨtə/ roh-DOF-fit-tə or /ˌroʊdəˈfaɪtə/ ROH-də-FY-tə; from Ancient Greek: ῥόδον rhodon, "rose" and φυτόν phyton, "plant"), are one of the oldest groups of eukaryotic algae, and also one of the largest, with about 5,000–6,000 species of mostly multicellular, marine algae, including many notable seaweeds. Other references indicate as many as 10,000 species; more detailed counts indicate about 4,000 in about 600 genera (3,738 marine species in 546 genera and 10 orders (plus...
