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...
