Spectral Diversity and Regulation of Coral Fluorescence in a Mesophotic Reef Habitat in the Red Sea
Photographs show the appearance of representative specimens under daylight (left column) or imaged under blue light through a yellow long-pass filter (Nightsea) (middle column). Fluorescence spectra (right column) were recorded after excitation with 450 nm light. Peak positions are indicated by arrows. (a) Oxypora egyptensis, (b) Alveopora ocellata, (c) Goniopora minor, (d) Pleuractis granulosa and (e) Echinophyllia aspera.
