Silvertip Snapper

Dense aggregations of silvertip snapper pack the chimney section of the Blue Hole, hanging in the water column and filtering the current that funnels through the narrow passage. The interplay of their silver flanks with filtered blue light from above creates one of Kosrae's most photographed underwater tableaux. These aggregations are a reliable feature of the dive regardless of season, as the structure provides shelter and the current delivers a continuous food supply.
