A small blenny on a massive coral in the Wessel Marine Park

A small blenny (Ecsenius yaeyamaensis) on a massive coral. There are over 300 known species of blennies globally, most of which are restricted to tropical regions with only a few found in cool-temperate waters. Blennies are small bottowm-dwelling fish, and this particular species is commonly observed in shallow coastal reefs where it perches on boulders and live coral heads in areas of abundant coral growth.
