Settlement of F. ancora planulae

Planulae settled on coral debris and ceramic tile, but not on plastic dishes, microscope slides, or CCA ( Fig. 4A ). The highest settlement rate was observed on coral debris (17.5%, Fig. 4B ), and some settled larvae metamorphosed into primary polyps with skeletons ( Fig. 4C ).

Fig. 4. Settlement of F. ancora planulae on different substrates. A: Results of settlement assay. Microscope slide (glass), crustose coralline algae, coral debris, or ceramic tile was added to plastic culture dishes (9 cm) filled with 30 mL of FSW. Then, 20 planulae (at 64–128 hpf) were added to each dish and maintained for 6 days. A dish with 30 mL of FSW, but no substrate was used as a control. The number of larvae settled on each dish surface or substrate was determined at 6 days of culture. Experiments were performed three times using planulae collected from different colonies. Data are shown as means ± SEs (n = 3 experiments). Groups with different letters are statistically different (p <0.05). B: Micrograph of larvae settled on coral debris. C: Micrograph after metamorphosis.
