Sieve-patterned Moray

Found singly during the day, in recesses of the reef, over estuaries, harbours, lagoons and tide-pools, in the open foraging for food at night. Regular visitor to Sydney Harbour although very shy!
Western Pacific - Eastern Australia

Morays open and close their mouths to move water through their gills for respiration.
This behaviour can often be seen as a threat especially towards divers, in fact this is far from the truth, they are very shy creatures and will only attack if provoked!
