Mary Roach Quote
The study animal of choice for taste 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.
