Adult cleaner wrasse outperform capuchin monkeys, chimpanzees and orang-utans in a complex foraging task derived from cleaner--client reef fish cooperation. [PDF]
PLoS ONE, 2012 The insight that animals' cognitive abilities are linked to their evolutionary history, and hence their ecology, provides the framework for the comparative approach. Despite primates renowned dietary complexity and social cognition, including cooperative

Cleaner wrasse failed in early testing stages of both visual and spatial working memory paradigms [PDF]
Animal CognitionWorking memory (WM), an attention-based short-term storage system responsible for the manipulation and integration of past knowledge with present information for goal-directed behavior, is a key executive function and a principal predictor of general ...

Cleaner fish escape salmon farms and hybridize with local wrasse populations [PDF]
Royal Society Open Science, 2018 The genetic impact of farmed fish escaping aquaculture is a highly debated issue. However, non-target species, such as cleaner fish used to remove sea lice from farmed fish, are rarely considered.

Cortisol mediates cleaner wrasse switch from cooperation to cheating and tactical deception [PDF]
Hormones and Behavior, 2014 Recent empirical research, mostly done on humans, recognizes that individuals' physiological state affects levels of cooperation. An individual's internal state may affect the payoffs of behavioural alternatives, which in turn could influence the ...

Rapid self-recognition ability in the cleaner fish [PDF]
Scientific ReportsWhether animals are self-aware has important implications for our approaches to both animal cognition and animal welfare. A landmark moment in animal cognition research was when great apes passed the mark-test and demonstrated mirror self-recognition ...

Does sedation with AQUI-S® mitigate transport stress and post transport mortality in ballan wrasse (Labrus bergyltae)? [PDF]
Frontiers in Veterinary ScienceBallan wrasse (Labrus bergylta) are commonly used as cleaner fish in salmon farms as a biological treatment to mitigate sea lice infestation. Improved welfare for cleaner fish both during production of these fish and when in sea-cages with salmon is ...

The Rock Cook Wrasse Centrolabrus exoletus Aims to Clean
Frontiers in Ecology and Evolution, 2019 Cleaning behavior between teleost fish in the marine environment is known to be a classic example of mutualistic cooperation, in which cleaners and their so-called clients exchange benefits. These mutualisms occur globally.

"Fair” outcomes without morality in cleaner wrasse mutualism [PDF]
Behavioral and Brain Sciences, 2017 Baumard et al. propose a functional explanation for the evolution of a sense of fairness in humans: Fairness preferences are advantageous in an environment where individuals are in strong competition to be chosen for social interactions.

Gene losses, parallel evolution and heightened expression confer adaptations to dedicated cleaning behaviour [PDF]
BMC Biology, 2023 Background Cleaning symbioses are captivating interspecific interactions in which a cleaner fish removes ectoparasites from its client, contributing to the health and diversity of natural fish communities and aquaculture systems.
