Are animals really superhumans?
We need to be very careful when making cross-species comparisons and shouldn't use ourselves as the standard against which others are measured.
All of the researchers who partook in the above study "caution that the processes underlying such 'superficially similar' cognitive behaviour are not known, and that - as previous commentators have stated - complex behaviour doesn't always reflect a complex mind." My own take is that we need to be very careful how we use the word "complex", and there seems to be no reason to think that fish minds aren't very complex even if they may not be as complex as the minds of great apes. We really don't have very good measures of mental complexity that can be used in cross-species comparisons, and clearly, small fish brains serve the fish rather well, as do small bee brains (please see "The Birds and the Bees and Their Brains: Size Doesn't Matter").
Along these lines, I became aware of the fish-eel study right after watching a BBC TV show called "Superhuman Animals" and thought about how cross-species comparisons can be misleading and fraught with error. I wondered if some other animals are really "superhuman" because, for example, they can do things that we cannot do because they have incredibly sensitive eyes, noses, or ears and can see, sniff, and hear things that we are unable to perceive? Why are we -- and should we be -- the standard against which other animals are compared? Perhaps, in some arenas, we are actually "wee animals" when compared to others.
