For 3 specimens – V1, V2 and V5 – I have photos in both 2023 and early 2024; V1 exhibited about 75% dieback in the interval, V2 and V5, 100%. Dieback is attributed to one or more extreme warming/coral bleaching events in 2023.
For 6 specimens NOT observed in both 2023 and 2024:
V3: Feb 6, 2020 – toppled and turned over; all still living
V4: Mar 3, 2019, all living
V6: Mar 7, 2019, all living
V7: Mar 23, 2015, all living
V8: Mar 10, 2024, appears unaffected by coral bleaching in 2023
V9: Apr 6, 2024, entirely dead
