  • The health benefits of massage therapy, like the reduction of stress, have so far only been shown in humans. This study uses modelling to demonstrate that, while visiting cleaner fish to have ectoparasites removed, the physical stimulation also acts to reduce stress in the coral reef fish,Ctenochaetus striatus.

  • The evolution of cooperation between unrelated individuals is a puzzle that attracts interest both in the social and in the natural sciences. Theoretical concepts may fail to capture essential features of real life cooperation. This paper focuses on the cleaning mutualism between cleaner wrasse and their client fish. A game theoretical model predicts that two providers should offer a higher service quality to clients than single providers, as long as they cooperate among each other. Field observations and an experimental test confirm the model prediction.
