FIGURE 3. Alcyonidium bullitum n. sp., Junghwadong, Baengnyeong Island. A. Very young colony encrusting sea grass with tentacle crowns expanded (MBRBKP4). B. Large multilayered colony enveloping a crab from deeper water, including its eye (BKF1). C. Another view of seagrass colony in A. D. Preserved rock-encrusting colony showing position of retracted polypides (BKF1). E. SEM image of dried surface of colony from enveloped crab, showing area with protruding orifices and tips of tentacle sheaths of many autozooids (BKF1). F. Part of crab-encrusting colony surface with mostly kenozooids, some still with bubble-like frontal membranes, others collapsed (BKF1). Scale bars: A, C = 0.50 mm; D = 0.60 mm; E, F = 0.10 mm.
