Sensitivity Differences in Fish Offer Near-Infrared Vision as an Adaptable Evolutionary Trait

Abstract

Near-infrared (NIR) light constitutes an integrated part of solar radiation. The principal ability to sense NIR under laboratory conditions has previously been demonstrated in fish. The availability of NIR in aquatic habitats, and thus its potential use as a cue for distinct behaviors such as orientation and detection of prey, however, depends on physical… (More)
