We’ve known for a while that the ocean is rapidly becoming too acidic for some forms of marine life to survive. We know that this is caused by continued rising emissions of carbon dioxide, which dissolves from the atmosphere into the ocean to form carbonic acid, which in turn dissolves/corrodes calcium carbonate-based coral reefs and shellfish.
Now we also know that ocean acidification does more than break down marine skeletons—it can actually cause behavioral changes in individual organisms. Simply stated, ocean acidification is making fish anxious—or, at least, anxiety as we measure it in fish.
what does it mean for a fish to be anxious?
