<p>Surveys were conducted at octocoral communities in St John, US Virgin Islands, in February and March 2016. Building on our previous studies on the environmental impact of octocoral community structure (Tsounis and Edmunds 2017; Tsounis et al. 2018), the present study was conducted at East Cabritte, Europa Bay, and East Tektite, within the Virgin Islands National Park, along the south shore of St. John.</p>
<p>Hypothesis (2) was tested: The role of individual fish feed more intensely near octocoral colonies than away from them, because they are safer due to visual cover.</p>
<p>Methods: In order to provide a broader characterization the habitat, other features of the benthos were measured using quadrats (1 × 2 m) that were surveyed for fish foraging behavior. Each of these quadrats was censused for the number of scleractinian corals, octocorals, and demospongia (pooled among species within each broad taxon). Scleractinians were counted regardless of colony size, and a colony was defined by an autonomous area of tissue. Colonies of octocorals > 5 cm tall were counted if their holdfasts were in the quadrat, and demospongia were counted based on the presence of discrete areas of biomass that were unconnected to other sponges.</p>
<p>Locations within each of the three sites were defined as within canopy ("in") if at least two large octocoral colonies were present in the quadrat. Where this criterion was not met, the area was categorized as outside of canopy ("out"). "Large colonies" were defined by the estimated mean height of arborescent octocorals at each site, and thus differed among sites. Large colonies were > 20 cm tall at Europa Bay and East Tektite, and > 30 cm tall at East Cabritte. </p>
