Good point. The initial experiment couldn’t even have been carried out without the biological definition of the fish category. If I’m asked to rate various fish as more or less typical, on a scale of 1 to 10, then I’ll give very different answers depending on whether 1 means “least typical of all biologically-defined fish” or “mammal” or “flower” or “pair of headphones”.
