“The study animal of choice for researchers is the catfish, simply because it has so many receptors. They are all over its skin. ‘Catfish are basically swimming tongues,’ says Rawson. It is a useful adaptation for a limbless creature that locates food by brushing up against it; many catfish species feed by scavenging debris on the bottom of rivers.
I try to imagine what life would be like if humans tasted things by rubbing them on their skin. Hey, try this salted caramel gelato, it’s amazing.”
