Additional File 2 Red fluorescent fish. MPG video clip showing fluorescent fish under "normal" viewing conditions versus conditions emphasizing red fluorescence. Sequence 1a: Redeye goby (Bryaninops natans) (field at ca. 17 m depth, using, natural daytime illumination, no filter). Sequence 1b: Several groups of Bryaninops natans showing red fluorescence (in the field at 25–18 m depth, using Canon PowerShot G7 and Sony HD HDR-CX6EK under natural daytime illumination through red filter, post-processed to highlight reds). Sequence 1c: Bryaninops natans individual under changing viewing conditions (laboratory with blue illumination, moving red filter, using Canon PowerShot G7). Sequence 2a: Pseudocheilinus evanidus in its natural environment (field at 25 m, using Canon PowerShot G7, natural daytime illumination, no filter). Sequence 2b: Pseudocheilinus evanidus showing red fluorescence (field at 25 m, using Canon PowerShot G7 and Sony HD HDR-CX6EK, natural daytime illumination, red filter, post-processed to highlight reds). Sequence 3a: Ctenogobiops maculosus at the entrance of its burrow (field at 17 m, using Sony HD HDR-CX6EK, natural daytime illumination, no filter). Sequence 3b: Ctenogobiops maculosus showing red fluorescent eyes (field at 17 m, natural daytime illumination, red filter, post-processed to highlight reds). Sequence 4a: Ctenogobiops tangaroai under broad spectrum light (laboratory, using Sony HD HDR-CX6EK, white light form halogen source, no filter). Sequence 4b: Ctenogobiops tangaroai highlighting red fluorescence under blue light (laboratory, using Sony HD HDR-CX6EK, white light form halogen source filter through scuba-blue filter, recording through red filter, not post-processed). Sequence 5: Eviota pellucida ( C. tangaroai in background) highlighting red fluorescence under blue light (laboratory, white light form halogen source filter through scuba-blue filter, recording through red filter, not post-processed). Sequence 6a: Enneapterygius abeli showing crypsis in large part of spectrum (laboratory, using Canon PowerShot G7, cold light source, no filter). Sequence 6b: Enneapterygius abeli showing red fluorescence (laboratory, using Canon PowerShot G7, blue light source, red filter, no post-processing). Sequence 7a: Corythoichthys schultzi showing cryptic colouration (field at ca. 20 m depth, using Sony HD HDR-CX6EK, natural daytime illumination, no filter). Sequence 7b: Corythoichthys schultzi showing red fluorescence (field at ca. 20 m depth,, natural daytime illumination, red filter, post-processed to emphasize red fluorescence).

Additional File 3 Fish showing behaviour indicative of signalling with red fluorescence . MPG video clip showing examples of fish behaviours that seem to involve red fluorescence. Sequence 1 : Corychthoichthys schultzi pair interacting, showing use of bright tail fan (field, ca. 20 m depth, using Sony HD HDR-CX6EK, natural sunshine illumination with red filter, post-processed to highlight reds). Sequence 2a : Enneapterygius destai individual showing extreme crypsis (specimen sits in the middle, lower half, swims briefly to top right at end). Sequence 2b : Enneapterygius destai individual showing red fluorescence of eye and first dorsal fin. Note visibility of gaze orientation and waving of first dorsal fin caused by excitement (laboratory, blue illumination, using Canon PowerShot G7, red filter).
