Without the zooxanthallae, the tissue of the coral animal appears transparent and the coral's bright white skeleton is revealed.</div><a id="bleachedHover" onmouseover="bleached()" onmouseout="hideBleached()" style="cursor: help; color: yellow; border-bottom: 1px dashed yellow;">bleached corals</a> on their journey.\n\nSimilar reports have also been flowing in from local research stations on Heron Island and One Tree Island.\n\nYour boss has asked you if remote sensing could be used to investigate the extent of the bleaching.
