Increasing levels ofArtificialLightAtNight (ALAN) alter the natural diel cycles of organisms at global scale. ALAN constitutes a potential threat to the light-dependent functioning of symbiotic scleractinian corals, the habit-founders of warm, shallow water reefs. Here, we show that ALAN disrupts the natural diel tentacle expansion and contraction behaviour, a key mechanism for prey capture and nutrient acquisition in corals. We exposed four symbiotic scleractinian coral species to different ALAN treatments (0.4–2.5 μmol quanta m−2s−1). Exposure to ALAN levels of 1.2 μmol quanta m−2s−1and above altered the normal tentacle expansion response in diurnal species (Stylophora pistillataandDuncanopsammia axifuga). The tentacle expansion pattern of nocturnal species (Montastraea cavernosaandLobophyllia hemprichii) was less affected, which may indicate a greater capacity to tolerate ALAN exposure. The results of this work suggest that ALAN has the potential to affect nutrient acquisition mechanisms of symbiotic corals which may in turn result in changes in the coral community structure in shallow water reefs in ALAN-exposed areas.
