Comments P.5332 right column 3rd paragraph: "Second, compared to corals, sponges are more often aphotosynthetic, but the presence of photosynthetic symbionts can occur in up to 85% of the sponges within a community (primary source). The most common photosymbionts in sponges are cyanobacteria (Usher 2008), with others belonging to Symbiodinium, Chlorophyta, Rhodophyta or diatoms (Taylor et al. 2007). The number of putative species (‘types’) of Symbiodinium in corals as a whole exceeds one hundred (see Table 1), while photosymbiont species diversity in sponges is not well characterized. By comparison, only three Symbiodinium types are known from the two tropical Exaiptasia species (Thornhill et al. 2013)."
