The skeleton of reef-building corals harbors diverse microbial communities that can supply energy to the coral host tissues and might have an integral role in holobiont nutrient cycling. However, we are lacking functional insight of the endolithic microbiome at large. In particular, the link between endolithic microbiome diversity and encoded genomic potential to supply energy to the coral host during coral bleaching, in the absence of their Symbiodiniaceae photosymbionts, remains poorly understood. Here we assembled endolith bacterial MAGs from DNA of coral skeletons from Goniastrea edwardsi and Porites lutea, two common reef‐building corals from the central Red Sea.
