Juvenile cleaner fish can socially learn the consequences of cheating [PDF]
Nature Communications, 2020 Cleaner fish can cheat clients for higher rewards but this comes with a risk of punishment. Here, Truskanov et al. show that juvenile cleaner fish can learn by observing adults to behave more cooperatively themselves but also to prefer clients that are ...

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 ...

Brain morphology predicts social intelligence in wild cleaner fish [PDF]
Nature Communications, 2020 The causes and consequences of social intelligence are challenging to establish. A study on wild cleaner fish reports that large forebrains enable individuals to score higher in a social competence test, suggesting forebrain size is important for complex

The potential for cleaner fish‐driven evolution in the salmon louse Lepeophtheirus salmonis: Genetic or environmental control of pigmentation? [PDF]
Ecology and Evolution, 2021 The parasitic salmon louse represents one of the biggest challenges to environmentally sustainable salmonid aquaculture across the globe. This species also displays a high evolutionary potential, as demonstrated by its rapid development of resistance to ...

Do cleaning organisms reduce the stress response of client reef fish? [PDF]
Frontiers in Zoology, 2007 Background Marine cleaning interactions in which cleaner fish or shrimps remove parasites from visiting 'client' reef fish are a textbook example of mutualism. However, there is yet no conclusive evidence that cleaning organisms significantly improve the

From learning to reversal learning: How non-cleaner fish tackle the biological market task [PDF]
Animal CognitionThe biological market task – also known as the ephemeral reward task – models the mutualistic cleaning interactions between bluestreak cleaner wrasses and their client fish on coral reefs.

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.

Cleaner fish with mirror self-recognition capacity precisely realize their body size based on their mental image [PDF]
Scientific ReportsAnimals exhibiting mirror self-recognition (MSR) are considered self-aware; however, studies on their level of self-awareness remain inconclusive.

Long-term effects of the cleaner fish Labroides dimidiatus on coral reef fish communities. [PDF]
PLoS ONE, 2011 Cleaning behaviour is deemed a mutualism, however the benefit of cleaning interactions to client individuals is unknown. Furthermore, mechanisms that may shift fish community structure in the presence of cleaning organisms are unclear.

Ultraviolet-B wavelengths regulate changes in UV absorption of cleaner fish Labroides dimidiatus mucus. [PDF]
PLoS ONE, 2013 High-energy wavelengths in the ultraviolet-B (UVB, 280-315 nm) and the UVA (315-400-nm) portion of the spectrum are harmful to terrestrial and aquatic organisms. Interestingly, UVA is also involved in the repair of UV induced damage.
