Dissimilarity (Bray-Curtis) dendrogram of the 47 stations on Serrana Bank with presence of gorgonian corals. The dashed line shows the dissimilarity division among groups. Roncador Bank Sixty-six benthic categories among species, genera, and functional groups of sessile organisms were found on Roncador Bank lagoonal and leeward reefs; fore-reef habitats could not be visited due to rough sea conditions. We observed 43 species of reef-building corals, 12-29 () species recorded per station

Roncador Bank Sixty-six benthic categories among species, genera, and functional groups of sessile organisms were found on Roncador Bank lagoonal and leeward reefs; fore-reef habitats could not be visited due to rough sea conditions. We observed 43 species of reef-building corals, 12-29 () species recorded per station, and coral cover from to 41%. Overall, fleshy macroalgae were the most abundant sessile reef dweller on the sampled stations (10-59%) followed by hard corals (), filamentous algae (), calcareous macroalgae (), and lesser amounts of other sessile benthic organisms (Fig. 17: Table 7). The benthic community cluster analysis revealed three minimal groups with less than 40% dissimilarity (Fig. 18). Cluster A only had two stations corresponding to shallow ( m) lagoonal reefs, probably on small not- mapped 'Acroporapalmata- Diploria habitats intermingled with 'Montastraea' ( Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Smithsonian Institution.
