Sponge distribution and the presence of photosymbionts in Moorea, French Polynesia [PDF]

open access: yesPeerJ, 2016
Photosymbionts play an important role in the ecology and evolution of diverse host species within the marine environment. Although sponge-photosymbiont interactions have been well described from geographically disparate sites worldwide, our understanding
