Glass Beach Tidepools

 

Clown Nudibranch (Triopha catalinae)

The nudibranch was upside-down, clowning around, when I first spotted it. The poor thing was probably trying to keep its gills wet in an extremely shallow pool of water. I diverted more water to its pool, but it was still in a sandy food desert, so I picked it up in a mussel shell and moved it to a more diverse tidepool to wait out the very low tide of minus 1.7 feet at Glass Beach in Fort Bragg.

The tidepools at Glass Beach were impressive at such a low tide, and I wished I'd dressed appropriately for exploring them in more detail. As it was, I had to keep my shoes and pants dry which limited how far out I was willing to go. We stayed until the sun set and the full moon rose, a dramatic closing to an excellent afternoon.


This guy (possibly a white-spotted rose anemone, Urticina lofotensis) was snuggled in a deep recess of a huge rock, preventing me from getting any other visual angle on it.


A very well-camouflaged mossy chiton (Mopalia muscosa), slightly curled up among pebbles, sand, and tiny bits of sea glass.


This purple shore crab (Hemigrapsus nudus) was also very well-camouflaged.


This tiny six-rayed sea star (Leptasterias sp.) was showing off its even tinier tube feet.

This encrusting red sponge was a little one, but there were larger encrustations farther out.




All the sea stars I saw looked to be in pretty good shape, showing no sign of wasting disease.


Mussels and gooseneck barnacles share the bed.


This ochre sea star seemed to have lost some of its grip after become exposed above the water line.


This other tiny six-rayed star was showing off its underside.


My wife asked me to photograph this hermit crab because of its nacreous shell colors.


I just took it as a challenge to try to photograph this little tidepool sculpin.

I was interested in split between the dark aggregating anemones and the lighter ones that apparently lost their symbiotic algae.

Farther out than I could reach in my street clothes, I had to let my Lumix superzoom do the walking. It has been years, I think, since I last saw bat stars and leather stars in the wild, and those are some pretty big purple sea urchins out in the open near an even bigger red urchin.


The sea palms were pretty beat up, having peaked in spring and early summer.
