It made me think of how frogs or amphibians in general are considered to be sensitive indicators of toxins in the environment. Sort of the opposite of not noticing important but subtle changes around them. https://en.wikipedia.org/wiki/Bioindicator https://en.wikipedia.org/wiki/Bioindicator "Amphibians, particularly anurans (frogs and toads), are increasingly used as bioindicators of contaminant accumulation in pollution studies.[18] Anurans absorb toxic chemicals through their skin and their larval gill membranes and are sensitive to alterations in their environment.[19] They have a poor ability to detoxify pesticides that are absorbed, inhaled, or ingested by eating contaminated food.[19] This allows residues, especially of organochlorine pesticides, to accumulate in their systems." I feel like this has been a well known thing for all my life, and one of the references in the article is from 1981.
