Clownfish (IMAGE) University of Bristol Caption The orange clownfish Amphiprion percula. A new study published in Biology Letters by Steve Simpson (University of Bristol) and colleagues shows that when these fish are reared in dissolved CO2 concentrations predicted to occur in the ocean by the end of this century, auditory responses to predator-rich noises are lost. This suggests ocean acidification could have serious consequences for orientation, habitat selection and survival. Credit Matthew Wittenrich.
