Figure 5 Ontogeny of sws1 opsin gene expression in
damselfish species with two paralogs. The two SWS1 copies are classified
as short- and long-wavelength shifted based on Fig. 3. A.
akindynos and N. melas transition from expressing both copies at
the larval stage to only expressing sws1β at later stages. On the
contrary, most Pomacentrus species primarily express sws1α at the larval stage, shifting towards a more balanced expression of the
two sws1s in later stages.
