FIGURE 3. Dorid nudibranch sea slug Ancula lentiginosa Farmer 1964 and its white egg masses and entoproct prey, Myopedicellina spinosa, (Robertson, 1900) n. comb., in situ, low rocky intertidal, Tarantula Reef, Jalama Beach, 34.4949°, -120.4970°, Santa Barbara Co., CA, USA, photographed 7 July 2016. Photo courtesy of Jeff Goddard, Marine Science Institute, University of California, Santa Barbara. The nudibranch slug was only 4 mm long, but it looks like a giant in this "micro-forest" growing on the underside of a low intertidal cobble at Jalama. Myopedicellina spinosa are the translucent, wine-glass-shaped zooids bent over (probably in defensive posture) on their relatively thick and flexible stalks and visible underneath the slug and in the foreground. The skinny, semi-opaque white tubes at lower left appear to be zooids of a cyclostome bryozoan. The fuzzylooking stalks across the top and in front of the slug are colonial hydrozoans covered with translucent, branching colonial ciliates and a few brown benthic diatoms.
