It can be challenging to identify scleractinian corals from the genus Pocillopora (Lamarck 1816) in the field because of their large range of inter- and intra-specific morphological variation that co-occur with changes in the physical environment. This task is made more arduous in the context of a depth gradient, where light and water current could greatly affect the morphology of the corallum. Pocillopora verrucosa (Ellis and Solander, 1786) in Taiwan was previously reported exclusively from shallow waters (<10m in depth), but a recent observation of this species in the mesophotic zone (>40m in depth) questions this bathymetric distribution. We used the mitochondrial open reading frame and the histone 3 molecular markers to investigate the vertical and horizontal spatial distribution of P. verrucosa around Ludao (Green Island), Taiwan. We genotyped 101 Pocillopora verrucosa-like colonies collected from 4 depth zones, ranging from 7 to 45m, at 3 sites around the island. Of the 101 colonies sampled, 85 were genotyped as P. verrucosa, 15 as P. meandrina, and one specimen as an undescribed Pocillopora species. P. verrucosa was found at all depths, while P. meandrina and the undescribed Pocillopora specimen were limited to 15m depth. P. verrucosa has a large bathymetric distribution around Ludao and could benefit from the refuge that the mesophotic zone offers. This study illustrates the difficulty of identifying Pocillopora corals in the field and emphasizes the relevance of molecular taxonomy as an important and complementary tool to traditional taxonomy for clarifying vertical and horizontal species distribution. Our results also illustrate the need in conservation biology to target species genetic diversity rather than just species diversity.,Histone FASTA alignmentHistone 3 region alignment for all haplotype H1 to H9mtORF FASTA alignment dataMitochondrial Open Reading Frame alignment data for all samples,
