Repeated and Widespread Evolution of Bioluminescence in Marine Fishes

Fig 2

Evolutionary Relationships and Divergence Times of Ray-Finned Fishes Inferred from Eleven Gene Fragments.

Numbers at nodes correspond to ancestral-character-state-reconstruction distributions of the evolution of bioluminescence indicated in Fig 3. Blue branches and taxa labels indicate the presence of bioluminescence, all of which occur in marine habitats. Green taxa labels indicate additional marine taxa. Pink labels indicate lineages with marine and freshwater taxa, and white labels indicate lineages that are predominantly found in freshwater habitats.
