Mariposa negra con centro de las alas rojo y naranja en gradiente
Dolphins near some surfers. Too bad I only had the macro lens.
These pretty much dominate the floating docks at the Berkeley Marina, as far as I could tell. And by dominate I mean coat. Apparently they were introduced from the North Atlantic. Between Pacific Tides claims they require "relatively clean water." Does that mean Berkeley Marina is relatively clean? Seems doubtful...
Growing abundantly anywhere there was sun and fresh water.
