A) Phylogenetic analysis performed in this study recovered previously described four major opsin lineages – r-opsins, c-opsins, group 4 opsins and cnidopsins. Herein the C-opsins and cnidopsins form sister groups. (For details see Fig. S3), B) Detailed inspection of cnidopsin branch indicates extensive gene duplication and lineage-specific expansion of cnidarian opsins. (For details see Fig. S4).
