Porites lutea is a massive scleractinian coral (family Poritidae) and one of the most dominant reef-building corals across the Indo-Pacific, from the Red Sea to the Pacific. Its large, dome-shaped colonies with characteristic lemon-yellow or pale coloration when healthy can reach several meters across and are long-lived, recording decades of environmental history in their skeletal banding. The species is one of the most thoroughly studied Porites species in terms of growth physiology, symbiont diversity, and bleaching biology. Genomic data have been generated for this species and are available in public databases, enabling comparative studies of cnidarian evolution and ecology.
