Disappointed.
From the heading I was expecting ocean sunfish (Mola mola) getting all fighty. Those things are huge, they can weigh more than two tonnes!
Princeton University researchers investigating the behaviours of predatory fish have developed a kind of “video game” testing the feeding preferences of the bluegill sunfish. Describing their research target as “famously ravenous”, the researchers projected simulated prey onto one side of a tank – either as a single target, or …
"This experiment makes some very specific predictions about what's a good configuration and what's not a good configuration, ..."
It would be interesting if the optimal configuration/behaviour, that they found in their experiments, was not the one that was already exhibited by prey groups in the wild. (Since prey groups have had millions of years to refine their technique.)
How would you go about teaching a shoal of sardines to change their behaviour? Would it be morally right to do so?
