Gliding just in front of a rocky reef wall blanketed in dense algae and seaweed, a rabbitfish (*Siganus*)—a herbivorous species native to the Mediterranean ecosystem—comes into view. The fish’s dorsal coloration, a blend of olive green and brown, transitions into a silvery sheen toward its underbelly. It has been captured in the very moment its mouth is slightly agape—likely as it prepares to graze on the algae covering the rocks.
