Whether the SVH works in the marine realm is an open question. To answer it, we tested the ability of this hypothesis to retrieve coral reef fish biodiversity from two remote sensing platforms on a global transect of reef sites. From orbit, we trialed the multispectral and panchromatic bands of WorldView-2 (WV-2) which have a spatial resolution of 2.5 and 0.5 m, respectively. At 100 times finer resolution, we repeated the experiment using unpiloted aerial vehicle (UAV) data. Encouragingly, the SVH evidently works as well in water as has been reported on land. Spectral variability was positively correlated with fish diversity for all sensors, though the area in which the variability was computed (window size) was important. The strongest relationship between spectral variability and fish biodiversity (R = 0.48) was returned using UAV imagery corrected for surface artifacts via fluid lensing. Splitting fish into herbivores, corallivores, and piscivores revealed that different feeding strategies correlate to spectral variability at different scales. Based on our results, we contend that remote sensing data are underutilized when used to simply map benthic habitat. Spectral variation can clearly serve as a proxy for <em style="box-sizing:border-box;margin:0px;padding:0px;">in situ</em> reef biodiversity.</div></div></div></div><div style="box-sizing:border-box;margin:0px;padding:0px;" id="reading-assistant-main-body-section"> </div><ul class="issue-navigation u-margin-s-bottom u-bg-grey1" style="background-color:rgb(245, 245, 245) !important;box-sizing:border-box;font-size:16px;line-height:24px;list-style:none;margin-bottom:16px !important;margin-left:0px;margin-right:0px;margin-top:0px;overflow:hidden;padding:0px;" id="issue-navigation"><li class="previous move-left u-padding-s-ver u-padding-s-left" style="box-sizing:border-box;float:left;left:0px;margin:0px;padding:16px !important 0px 16px;"><a class="button-alternative button-alternative-tertiary u-display-flex button-alternative-icon-left" style="--sd-ui-button-alt-border-bottom-colour-hover:#eb6500;--sd-ui-button-alt-border-bottom-colour:transparent;--sd-ui-button-alt-border-bottom-width:2px;--sd-ui-button-alt-colour-focus:#eb6500;--sd-ui-button-alt-colour:#1f1f1f;--sd-ui-button-alt-cursor:pointer;--sd-ui-button-alt-font-size:1em;--sd-ui-button-alt-gap:calc(0.5em - 2px);--sd-ui-button-alt-icon-background-colour-hover:transparent;--sd-ui-button-alt-icon-background-colour:transparent;--sd-ui-button-alt-icon-border-colour-hover:#eb6500;--sd-ui-button-alt-icon-border-colour:#1f1f1f;--sd-ui-button-alt-icon-external-link-size:0.625rem;--sd-ui-button-alt-icon-fill-hover:#1f1f1f;--sd-ui-button-alt-icon-fill:#1f1f1f;--sd-ui-button-alt-icon-padding:0.5rem;--sd-ui-button-alt-icon-size:2.5rem;--sd-ui-button-alt-min-width:5.5rem;-webkit-box-align:baseline;align-items:baseline;background-color:rgba(0, 0, 0, 0);border-style:none;box-sizing:border-box;color:var(--sd-ui-button-alt-colour);cursor:var(--sd-ui-button-alt-cursor);display:flex !important;font-family:inherit;font-size:var(--sd-ui-button-alt-font-size);gap:var(--sd-ui-button-alt-gap);line-height:var(--sd-ui-line-height);margin:0px;min-width:var(--sd-ui-button-alt-min-width);padding:0px;text-decoration:none;user-select:text;word-break:break-word;" href="https://www.sciencedirect.com/science/article/pii/S1470160X24013165"><svg class="icon icon-navigate-left" style="-webkit-text-stroke-width:0px;color:rgb(31, 31, 31);font-family:ElsevierSans, Arial, Helvetica, Roboto, "Lucida Sans Unicode", "Microsoft Sans Serif", "Segoe UI Symbol", STIXGeneral, "Cambria Math", "Arial Unicode MS", sans-serif;font-size:16px;font-style:normal;font-variant-caps:normal;font-variant-ligatures:normal;font-weight:400;letter-spacing:normal;orphans:2;text-align:left;text-decoration-color:initial;text-decoration-style:initial;text-decoration-thickness:initial;text-indent:0px;text-transform:none;white-space:normal;widows:2;word-spacing:0px;" focusable="false" viewbox="0 0 54 128" height="20"><path d="M1 61l45-45 7 7-38 38 38 38-7 7z"></path></svg></a><br> </li></ul>
