Spectral Diversity and Regulation of Coral Fluorescence in a Mesophotic Reef Habitat in the Red Sea
Fig 5
Changes in fluorescence of colour morphs of Euphyllia paradivisa from mesophotic depths in response to altered light environments.
The daylight appearance and blue-light- induced fluorescence of the green (a), red (b) and yellow (c) colour morphs are imaged after one year of culture under low intensity daylight (upper row) and in complete darkness (lower row). Fluorescence emission spectra in the range of GFP-like proteins (450–650 nm) and chlorophyll (650–800 nm), measured by excitation with ~450 nm, are shown for the displayed individuals. Peak positions are indicated by arrows.
