Nature has carved two prominent limestone and basalt structures along Aireys Inlet Beach. These male Australian darters are drying their wings on top of Table Rock. Nearby is Eagle Rock, a tall volcanic stack. Surrounding their base is hormosira banksii. This slimy brown seaweed endemic to Australasia is commonly called Neptune’s necklace or Neptune’s pearls. These coastal waters are included in the 42 acre Eagle Rock Marine Sanctuary.
