Grey reef sharks cruise the wall edge throughout the year, using the drop-off as a patrol boundary for their territorial ranges. They are most active on incoming tides when prey fish concentrate around the reef crest, and groups of 3 to 8 individuals are regularly observed making passes at depth. The population at Yoro Reef appears to be resident rather than transient, with individually recognisable animals returning across seasons.
