Flatworms on disintegrated Botrylloides violaceus. The flatworms were identified as Cycloporus sp.
by Sigmer Quiroga and Leslie Newman on the Marine Flatworm facebook page, but later re-identified as more likely to be Eurylepta sp. (probably E. aurantiaca)
by Tony Phillips. E. aurantiaca was figured (PL 4.11) by Haderlie (1980) in his flatworm chapter in Intertidal Invertebrates of California.

The widely invasive bryozoan, Watersipora subtorquata, which fouls boats
and docks and is more tolerant of copper paint (e.g., anti-fouling paint) than most organisms. See here for more info:
