Phylogeny of corals with genomic and transcriptomic resources used in this study (A) with images of the two focal species, Acropora palmata (B) and Acropora cervicornis (C). The evolutionary relationships depicted in the coral phylogeny are redrawn based on the phylogenomic analysis by Bhattacharya et al. (2016), but branch lengths do not reflect evolutionary distance. Estimate of divergence time between the Caribbean acroporids and A. digitifera was calculated by Richards et al. (2013). Photographs of A. palmata (B) and A. cervicornis (C) were taken by Iliana B. Baums in Curacao (2018).
