More acidic oceans could soon start dissolving tuna fish as they swim, long before they make it to consumers’ plates.

This worrying news comes from a study published last month in the Journal of Experimental Marine Biology and Ecology which found that increasing acidification in the Pacific Ocean—a function of climate change—will cause staggering levels of damage to multiple organs in yellowfin tuna (Thunnus albacares) larvae.
