Though it seems pretty clear that this is a sculpin, I am unclear as to the species. I only guess tidepool because it was discovered in a tide pool! A huge tire left on the beach has filled with water and now acts as a tide pool full of creatures. This fish was about 9cm long, seemingly resting on the stone in the tide pool.
These small anemone (3-5cm across) completely cover the sandy areas of Mee Kwa Mooks. The two pictures included depict anemones from farther up the beach (furthest from the water) and others nearer the water. The anemone higher up on the beach are consistently covered in bits of shell, while the ones closer to the water are quite exposed. It seems that the bits of shell must be an adaptation to the greater exposure high up the shore- more time under the sun and in the open air. The bits of brilliant white hell would efficiently deflect UV rays from the delicate anemone. I am guessing that these are aggregating anemones, which means that they are clones of each other.
Troschel's Sea Star is not unlike the Ochre or Purple sea star except in that it's limbs are considerably slimmer and the central disk much smaller. This one was exposed on a rock at low tide, but at the very lowest portion of the inter-tidal zone, only about 1m from the water at the tide's lowest point.
On two separate parts of the beach I came across these squishy nudibranchs. Both were about 10cm long, and the second accompanied by long white ribbons of eggs! Nudibranch, means "naked lung" in latin, likely named for the soft and shaggy outer membrane of these creatures that they use to breathe. Both were very very soft and hardly reacted to my touching them. I was amazed at how quickly they moved!
We found this little nudibranch (sea slug) when we scooped water into a tray from a bed of eel grass. Here it is pictured on top of a sand collar. The body was only about 2 cm long. I am guessing it was a young nudibranch, but I don't think that this species grows all that much larger.
