Haliotis fulgens (green abalone) - this is our most common intertidal species of abalone. Note the distinctive shell sculpturing when the shell is not eroded.

A bright red mite, Neomolgus littoralis (Linnaeus, 1758), which moves very fast and is hard to photograph (but see next image).
image
Neomolgus littoralis is nearly cosmopolitan mite (an arachnid) living in the intertidal splash zone. There are only a few publications that I have seen, for example describing populations from Europe, California, and Japan. There are no DNA sequence comparisons across its widespread populations, so it is possible that it is a species complex of similar appearing species. This bright red mite can be found on the walls of the sea tunnels we were walking through, and also can be found under rocks or on drift kelp. It is mostly a predator. It has been observed eating insect larvae and nematodes. This is probably the best images I have taken of it. It is about 3 mm long, and moves rapidly.

These Littorina keenae (eroded periwinkles) are surrounded by acorn barnacles (probably both Balanus glandula and the smaller and brownish Chthamalus fissus).

The chiton, Lepidozona pectinulata, is common in SoCal on the underside of rocks. On the left it is dwarfed by a Stenoplax conspicua, but they can be perhaps 2 cm in length.

This is a female crab from the genus, Cancer. I expected it to be C. antennarius (Pacific rock crab), but it seems to lack the red spotting on its underside and that species has more setae on the carapace. I should have gotten better images.
