Tide Pools

Quick trip to Shell Beach at low tide 1035 hrs on Friday. Tide was only at 0.1. Two schools were there, one class on each side of the beach. I mainly went to check how the seaweeds were doing and to see if I could find any sea stars. The seaweeds were more robust but less varied. I saw no cystoseira at all, very little kombu or sea lettuce, no wakame (that's probably a good thing) and less feather boa and Turkish towel than I'd seen before. I forgot to look carefully for any sea palm in the distance, but didn't happen to see any. Nori/Laver was doing very well, covering many boulders. Saw other species that I wouldn't generally collect but practiced ID'ing them. Lots of small anemones on the rocks, but the only large one I found open I photographed. Usually I see more. Also, I didn't see a single sea star. Last visit I found three, which was very low. I'd like to learn more about the disease taking out the sea stars. This trip didn't seem all that rich overall; it could have been that I was moving too quickly past each pool, trying to stay ahead of the loud and destructive groups of kids, but it seemed like a less productive walk than usual. I only stayed a little more than an hour, picking up the trash left behind from the kids in the tide pools and decided to leave.

Was quite sure this was Turkish Towel but getting other ID's here. Will have to go back and get better photos and key it out.

Seemed more prolific here than in previous years. I chose a photo that was not entirely covered for contrast, but many of the boulders were black with nori.

This is my favorite coastal snack. For me it tastes the best right off the rock. Finally it's robust enough to eat - earlier in the year it was much smaller and also tasteless.

Most likely the color is bleached. Was found unattached in a tide pool at low tide. Several like this were found with exactly the same color.

This was on a boulder in a lower tidal zone than I expected and didn't feel as 'rough' as the name would suggest.

Hmm... no bladders. It's early-ish in the season so I'm hoping my ID is correct and it's just young. It's in a lower tide zone than the little rock weed which looks similar to me, but this species' branches are wider and flat like rounded blades.

Initially, I thought this was a Lithothamnion sp. but those grow as crusts. This species was quite common at Shell Beach in the lower tidal zones, still submerged at low tide.
