Among terrestrial organisms, biofluorescence has been commonly recorded in arthropods, but rarely from vertebrates （Lagorio et al. 2015）. It has long been known from parrots （Hausmann et al. 2003） and has recently been recorded from a frog （Taboada et al. 2017） and from chameleons （Chamaeleonidae： Protzel et al. 2018）.展开更多
