Georgia’s estuaries never disappoint when it comes to illustrating the various shapes, sizes and adaptations you can find in fish. This thought entered my mind the other day as I tried removing a tiny skilletfish (Gobiesox strumosus) that suctioned onto my hand during a recent sampling trip in Sapelo Sound. This tiny, flattened fish gets its name from its round, pan-like shape, but its most remarkable feature is the suction disc formed from its fused pelvic fins. This natural suction cup allows the skilletfish to cling tightly to hard surfaces like oysters, rocks, pilings, and even the hands of unsuspecting researchers!
Despite their small size and cryptic coloration, the skilletfish plays a unique role in the estuarine ecosystem. It often hides in oyster reefs and under submerged structures, feeding on small invertebrates while remaining nearly invisible to larger predators. This adaptation is particularly advantageous given coastal Georgia’s daily six to eight foot plus tides, which helps the skilletfish resist strong currents and avoid detection.

Cool fact: Female skilletfish will lay several hundred sticky, amber-colored eggs into an empty oyster shell, and males will guard the eggs until they hatch.
