[HTML][HTML] Daytime eyeshine contributes to pupil camouflage in a cryptobenthic marine fish
Ocular reflectors enhance eye sensitivity in dim light, but can produce reflected eyeshine
when illuminated. Some fish can occlude their reflectors during the day. The opposite is …

Cases where animals use controlled illumination to improve vision are rare and thus far
limited to chemiluminescence, which only functions in darkness. This constraint was recently …

Do the fluorescent red eyes of the marine fish Tripterygion delaisi stand out? In situ and in vivo measurements at two depths
Since the discovery of red fluorescence in fish, much effort has been invested to elucidate
its potential functions, one of them being signaling. This implies that the combination of red …

[HTML][HTML] The consistent difference in red fluorescence in fishes across a 15 m depth gradient is triggered by ambient brightness, not by ambient spectrum
Background Organisms adapt to fluctuations or gradients in their environment by means of
genetic change or phenotypic plasticity. Consistent adaptation across small spatial scales …
