Red-fluorescence-in-reef-fish-A-novel-signalling-mechanism?-1472-6785-8-16-S3

Description:

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).
