Data From Exercise 17

The article “Punishers Benefit from Third- Party Punishment in Fish” (Science, 8 Jan 2010: 171) describes an experiment meant to simulate behavior of cleaner fish, so named because they eat parasites off of “client” fish but will sometimes take a bite of the client’s mucus instead. (Cleaner fish prefer the mucus over the parasites.) Eight female cleaner fish were provided bits of prawn (preferred food) and fish-flake (less preferred), then a male cleaner fish chased them away. One minute later, the process was repeated.
