An animal that tries to remove a mark from its body is only visible when looking into mirror displays the capacity for self-recognition (MSR), which has been interpreted as evidence self-awareness. Conservative interpretations of existing data conclude convincing MSR currently restricted great apes. Here, we address proposed shortcomings previous study on in cleaner wrasse Labroides dimidiatus , by varying preexposure mirrors and marking individuals with different colors. We found (1) 14/14...
Some animals have the remarkable capacity for mirror self-recognition (MSR), yet any implications self-awareness remain uncertain and controversial. This is largely because explicit tests of two potential mechanisms underlying MSR are still lacking: mental image self kinesthetic visual matching. Here, we test hypothesis that ability in cleaner fish, Labroides dimidiatus , associated with a self, particular self-face, like humans . Mirror-naive fish initially attacked photograph models both...
Summary Sleep is a ubiquitous process that has been conserved in animals. Yet, our understanding of the functions sleep largely derives from few species. considered to play an important role mental processes, including learning and memory consolidation, but how widespread this relationship across taxa remains unclear. Here, we test impact disruption on ability cleaner fish ( Labroides dimidiatus ) both learn remember novel cognitive task. was disrupted by exposing subset light at set...
Abstract True individual recognition (TIR), the ability to distinguish multiple familiar members individually, is more elaborate than class-level recognition, and evidence for perform TIR reported from primates, some other social mammals, birds lizard in vertebrates. These animals exhibit a highly structure, wherein essential their interactions. Such high sociality has been documented fish, but clear of limited. The cichlid, Neolamprologus pulcher , cooperative breeder that guards territory,...
Despite competing for resources such as space, food and mates, many territorial animals are less aggressive towards neighbours who rarely go beyond their boundaries. This so-called dear enemy phenomenon is advantageous in defence, but it has not been well studied fish. In this work, we tested the ‘correct–incorrect boundary paradigm’ of using cichlid fish Neolamprologus pulcher , which exhibits relationships. When was placed a small experimental tank, established its territory, initially...
Abstract Human society is cooperative and characterized by spontaneous prosociality. Comparative studies on endotherm vertebrates suggest that social interdependence causes the evolution of proactive To test generality this hypothesis, we modify a prosocial choice task for application to convict cichlid, Amatitlania nigrofasciata , monogamous fish with biparental care strong pair bond. We also affirm male subjects learn favor choices when their mates are recipients in neighboring tank. When...
Many territorial animals reduce aggression toward their neighbours once boundaries are established. This relationship is called the dear enemy phenomenon, hypothetically based on a conditional strategy like tit for tat (TFT). However, studies such as male songbirds do not fully support this hypothesis. We tested TFT hypothesis in females of cichlid Neolamprologus pulcher, which exhibits relationships, under laboratory conditions. Focal fish attacked invading frequently strangers, but they...
Individual recognition is a necessary cognitive ability for the maintenance of stable social relationships. Recent studies have shown that like primates, some fish species can distinguish familiar from unfamiliar strangers via face-recognition. However, taxa studied are restricted (within Perciformes) and visual signal used remains unclear. Here, we investigated individual-recognition in males sexually dichromatic guppy (Poecilia reticulata, Cyprinodontiformes). Using males, examined...
ABSTRACT Sleep is ubiquitous across animal taxa. Strong evolutionary pressures have conserved sleep over the history of animals, yet our understanding functions still largely derives from mammals and select laboratory models. considered to play an important role in mental processes, including learning memory consolidation, but how widespread this relationship occurs taxa remains unclear. Here, we test impact disruption on ability cleaner fish (Labroides dimidiatus) both learn then remember a...
Social vertebrates often recognise familiar individuals by facial recognition, a basal cognitive ability which animals establish stable sociality, including territoriality. The three-spined stickleback (Gasterosteus aculeatus), model species for behavioural studies, is territorial; its to visually remains unclear. Here, we report that this has individual-specific colour morph features and can recognition. Territorial neighbours of the same sex established dear enemy relationship with each...
Cleaner fish can recognize cognitively their own images in mirrors and portraits as themselves via self-face recognition. For recognition of the self, they have an internal mental image like humans. This process suggests private self-awareness or “mind” a concept self.
