The scales covering the elytra of the male Hoplia coerulea beetle contain fluorophores embedded within a porous photonic structure. The photonic structure controls both insect colour (reflected light) and fluorescence emission. Herein, the effects of water-induced changes on the fluorescence emission from the beetle were investigated. The fluorescence emission peak wavelength was observed to bl...

The study reports massive and dense Blue coral Heliopora coerulea (Pallas, 1766) population in Chetlat atoll, one of the northernmost atolls Lakshadweep Archipelago. Globally, there are only a few instances occurrence such blue populations, mostly from Japan. Underwater survey shows that about 60 % entire reef area is occupied by coral. In addition, this atoll was observed to have lesser cover ...
