With the ongoing of global warming trend, the frequency of MHWs is expected to increase. So, the ability of corals to adapt to or recover from extreme heat stress will be crucial for their survival in the future. We found that Turbinaria peltata was adaptable to high temperatures, which was demonstrated by a reduced coral response to the second heatwave strike, indicated by the decreased loss of the density of zooxanthellae and the content of antioxidant-related enzymes. Decreased abundance of pathogenic bacteria and increased abundance of beneficial bacteria in symbiotic bacteria.
