The past, present and future of cleaner fish cognitive performance as a function of CO 2 levels
Ocean acidification is one of the many consequences of climate change. Various studies suggest that marine organisms' behaviour will be impaired under high CO 2 . Here, we show that the cognitive performance of the cleaner wrasse , Labroides dimidiatus , has not suffered from the increase of CO...

Ocean acidification is one of the many consequences of climate change. Various studies suggest that marine organisms' behaviour will be impaired under high CO 2 . Here, we show that the cognitive performance of the cleaner wrasse , Labroides dimidiatus , has not suffered from the increase of CO 2 from pre-industrial levels to today, and that the standing variation in CO 2 tolerance offers potential for adaptation to at least 750 µatm. We acclimated cleaners over 30 days to five levels of pCO 2, from pre-industrial to high future CO 2 scenarios, before testing them in an ecologically relevant task—the ability to learn to prioritize an ephemeral food source over a permanent one. Fish learning abilities remained stable from pre-industrial to present-day pCO 2 . While performance was reduced under mid (750 µatm) and high CO 2 (980 µatm) scenarios, under the former 36% of cleaners still solved the task. The presence of tolerant individuals reveals potential for adaptation, as long as selection pressure on cognitive performance is strong.
