The Covert World of Fish Biofluorescence: A Phylogenetically Widespread and Phenotypically Variable Phenomenon

Figure 2

Observed occurrences of green and red fluorescent emissions indicate the evolution of biofluorescence is widespread across the evolutionary history of ray-finned fishes (Actinopterygii).

Family-level tree showing evolutionary relationships of ray-finned fishes inferred from maximum likelihood analysis of 221 species and six (one mitochondrial, five nuclear) genes. Note: Not all biofluorescent lineages are shown due to sampling limitations (see Table S1, Fig. S1).
