Study localities: 1 = El Quseir (Sharm Fugani, Egypt, field); 2 = Dahab Marine Research Centre (South Sinai, Egypt, field and laboratory), 3 = Lizard Island Research Station (Queensland, Australia, field and laboratory), 4 = Tübingen (laboratory), 5 = Collection JH, Vienna. Fluorescent body parts are encoded as follows: 1 = Eye rings, 2 = Head (dorsal), 3 = Lateral lines, 4 = Trunk, 5 = First dorsal fin, 6 = Anal fin, 7 = Tailfin, 8 = Snout, 9 = Dots on body, 10 = Spine, 11 = Gut. Strength of fluorescence is a consensus measure among observers based on visibility in the field and/or the laboratory: Strong (+++) means strikingly bright in the field as well as in the laboratory, easy to photograph and strong spectrometric signal; weak (+) means only visible under laboratory conditions, requiring long integration times for fluorescence measurement and long exposure times for photography (optimized for each specimen). Peak emission is shown as 5 nm interval.
