Sometimes there seems to be a color scheme for the day. Today I helped Eric with field work at Van Damme State Park in Mendocino County. Between tasks I took a few photos, where reds and purples kept appearing.
Red Urchin (Strongylocentrotus franciscanus) among Purple Urchins (S. purpuratus)
Close-up of a Gumboot Chiton (Cryptochiton stelleri)
A very small (~1 cm across) Ochre Seastar (Pisaster ochraceus)
An elegant scale worm in a shallow pool (not certain of the species)
The day started with an intense squall line approaching from the horizon. It moved very quickly across the ocean towards land. I barely had time to take this picture before it started to pour!
