Damage happens often by mix of storms, earthquakes and destructive fishing practices. \nThis colony has a good overgrowth of dead portions, a high lesion repair. The white edges are the growth zones.\nIn 2023, when this photo was taken, the stress resistance, recovery, and overall reef health and resilience potentials of this coral community were all high.\nKarang Huisman, Tayandu Island, Indonesia, \n5°28'41.72 S 132°13'21.31 E at 11m depth
