A cold winter dive with water temperature of 43F. At least the distance from car to water is short at this location with the bottom step of the access in the water at high tide.
This is the only location I have seen the Twelve-Tentacled Parasitic Anemone (Peachia quinquecapitata) also known as Jelly-Dwelling Anemone.
There is some great information on this creature here:
