Fish size themselves up in a mirror to decide if they can win a fight

Cleaner wrasse use their reflection to build a mental image of their body size, which they use to compare themselves to rivals before picking a fight

Before deciding whether or not to fight another fish, cleaner wrasse check their own reflection in a mirror and size themselves up. Bluestreak Cleaner Wrasse (Labroides dimidiatus) are remarkably bright. These finger-sized coral reef fish were the first fish to pass the mirror test, a common assessment to see whether an animal recognises that the reflection is of its own body and not another animal. Researchers have now found that these wrasses use their likeness to construct a mental image of their body size, which they can compare to others...

Bluestreak cleaner wrasses (Labroides dimidiatus) are fundamental in coral ecosystems, as they remove parasites from fishes, keeping them healthy, and according to a recent study, they may be self-aware as these small fishes can recognize theyself in photos and mirror, an ability usually attributed to humans and large mammals. According to researchers, self-awareness may be more widespread among animals than previously thought.

Cleaner fish, likely recognize their own mirror image using a mental image of the self-face comparable to humans. Mirror-naïve fish frequently attacked photographs of both themselves and strangers. In contrast, after passing the mirror test, aggression against their own photograph and composite photographs of own face/stranger body declined, but aggression remained toward unfamiliar and composite photographs of stranger face/own body. These results suggest that cleaner fish with mirror self-recognition ability can recognize their own mirror image based on a mental image of their own face, rather than by comparing body movements in the mirror

I have tried to choose a wide distribution of animals representing many different clades, aiming for relatively intelligent species within their respective clade. There are only 12 poll options possible, so no asking “what about X?” Inevitably some species will have to stand in for a much broader class than others, e.g., the Humboldt squid for all cephalopods. (But the Humboldt squid is probably a good choice: they’re fairly gregarious and cooperative, unlike the octopus.)

Uplifted species will have the capacity for language, abstract thought, tool use, episodic memory, planning, and self-awareness. Their cognition may in other respects be radically different from our own, especially if they are not mammals.

Fishuary 2024: Day 10 - Symbiotic relationship @fish-daily

For this one I chose a bluestreak cleaner wrasse (Labroides dimidiatus) and a roving coral grouper (Plectropomus pessuliferus). They're hanging out.

I keep telling myself that if I continue making one or two fishes a day I might catch up and do all of Fishuary. At this point it's still possible, just a matter of willpower and pacing!

According to a study done in 2019, cleaner wrasses were the first fish observed to pass the mirror test. The bluestreak cleaner wrasse (Labroides dimidiatus) is a tiny tropical reef cleaner fish. Cleaner fish have an adapted evolutionary behavior in which they remove parasites and dead tissue from larger fish. When put through the mirror test, using a benign brown gel injected into the skin of the fish, and resembling a parasite, the cleaner wrasse showed all the behaviors of passing through the phases of the test. When provided with a colored tag in a modified mark test, the fish attempted to scrape off this tag by scraping their bodies on the side of the mirror. Gordon Gallup believes the cleaner wrasses' behavior can be attributed to something other than recognizing itself in a mirror. Gallup has argued that a cleaner wrasse's job in life is to be aware of ectoparasites on the bodies of other fish, so it would be hyper aware of the fake parasite that it noticed in the mirror, perhaps seeing it as a parasite that it needed to clean off of a different fish. The authors of the study retort that because the fish checked itself in the mirror before and after the scraping, this means that the fish has self-awareness and recognizes that its reflection belongs to its own body. The cleaner wrasses, when tested, spent a large amount of time with the mirror when they were first getting acquainted with it, without any training. Importantly, the cleaner wrasses performed scraping behavior with the colored mark, and they did not perform the same scraping behavior without the colored mark in the presence of the mirror, nor when they were with the mirror and had a transparent mark. Following various objections, the researchers published a follow-up study in 2022, where they did the mirror test on a larger sample of wrasses and experimented with several marking techniques. The new results "increase[d] [the researchers'] confidence that cleaner fish indeed pass the mark test", although wrasses attempted to scrape off the mark only when it resembled a parasite.

This seems extremely dubious but I Want To Believe.

Impacto do IMC nas taxas de sobrevivência ao tratamento do câncerSobrevivência à obesidade e à imunoterapia Um estudo da Universidade Metropolitana de Osaka com mais de 500.000 pacientes com câncer de pulmão descobriu que um IMC mais alto reduziu o risco de morte durante a imunoterapia e a quimioterapia. No entanto, essa tendência se inverteu em um IMC de 24. Para aqueles com IMC abaixo de 28, a imunoterapia teve um risco menor do que a quimioterapia, mas para pacientes com IMC de 28 ou mais, a imunoterapia aumentou o risco. 2 horas atrás Novas espécies fósseis de peixes descobertas na Austrália OcidentalNovo peixe fóssil no mapa da tectônica de placas Em um novo estudo publicado na Nature Communications, cientistas liderados pela Flinders University e especialistas do Canadá, Austrália e Europa descobriram um antigo peixe celacanto primitivo do Devoniano excepcionalmente bem preservado na remota Austrália Ocidental. Esta descoberta fóssil sugere que a tectônica de placas também influenciou significativamente a origem e a extinção dos animais. O fóssil foi chamado de Ngamugawi Whangarei. Sua descoberta preenche uma lacuna significativa no período de transição na história do celacanto entre as formas mais primitivas e outras formas mais "anatomicamente modernas". 44 minutos atrás O gás ozônio está reduzindo o crescimento das florestas tropicaisAs florestas tropicais são “sumidouros de carbono” vitais O gás ozônio está reduzindo o crescimento das florestas tropicais – deixando cerca de 290 milhões de toneladas de carbono não capturadas a cada ano, mostra uma nova pesquisa. O novo estudo calcula que o ozônio ao nível do solo reduz o novo crescimento anual em florestas tropicais em 5,1% em média. O efeito é mais forte em algumas regiões – com as florestas tropicais da Ásia perdendo 10,9% do novo crescimento. 21 minutos atrás Os peixes limpadores percebem precisamente o tamanho do seu corpoEspelho meu, espelho meu, no meu aquário, quem é o maior peixe de todos?

A declaration signed by dozens of scientists says there is “a realistic possibility” for elements of consciousness in reptiles, insects and molluscs.

 Crows, chimps and elephants: these and many other birds and mammals behave in ways that suggest they might be conscious. And the list does not end with vertebrates. Researchers are expanding their investigations of consciousness to a wider range of animals, including octopuses and even bees and flies.

Armed with such research, a coalition of scientists is calling for a rethink in the animal–human relationship. If there’s “a realistic possibility” of “conscious experience in an animal, it is irresponsible to ignore that possibility in decisions affecting that animal”, the researchers write in a document they call The New York Declaration on Animal Consciousness. Issued today during a meeting in New York City, the declaration also says that there is a “realistic possibility of conscious experience” in reptiles, fish, insects and other animals that have not always been considered to have inner lives, and “strong scientific support” for aspects of consciousness in birds and mammals.

As the evidence has accumulated, scientists are “taking the topic seriously, not dismissing it out of hand as a crazy idea in the way they might have in the past,” says Jonathan Birch, a philosopher at the London School of Economics and Political Science and one of the authors of the declaration.

The document, which had around 40 signatories early today, doesn’t state that there are definitive answers about which species are conscious. “What it says is there is sufficient evidence out there such that there’s a realistic possibility of some kinds of conscious experiences in species even quite distinct from humans,” says Anil Seth, director of the Centre for Consciousness Science at the University of Sussex near Brighton, UK, and one of the signatories. The authors hope that others will sign the declaration and that it will stimulate both more research into animal consciousness and more funding for the field.

Blurry line

The definition of consciousness is complex, but the group focuses on an aspect of consciousness called sentience, often defined as the capacity to have subjective experiences, says Birch. For an animal, such experiences would include smelling, tasting, hearing or touching the world around itself, as well as feeling fear, pleasure or pain — in essence, what it is like to be that animal. But subjective experience does not require the capacity to think about one’s experiences.The consciousness wars: can scientists ever agree on how the mind works?

Non-human animals cannot use words to communicate their inner states. To assess consciousness in these animals, scientists often rely on indirect evidence, looking for certain behaviours that are associated with conscious experiences, Birch says.

One classic experiment is the mirror test, which investigates an animal’s ability to recognize itself in a mirror. In this experiment, scientists apply a sticker or other visual mark on an animal’s body and place the animal in front of a mirror. Some animals — including chimpanzees (Pan troglodytes)1, Asian elephants (Elephas maximus)2 and cleaner fishes (Labroides dimidiatus)3 — exhibit curiosity about the mark and even try to remove it. This behaviour suggests the possibility of self-awareness, which might be a sign of consciousness.

In an experiment with crows (Corvus corone)4, the birds were trained to make a specific head gesture whenever they saw a coloured square on a screen, a task they carried out with high accuracy. While the birds performed the task, scientists measured the activity in a region of their brain associated with high-level cognition. The birds’ brain activity correlated with what the birds were reporting, not with what they were actually shown. This suggests that they were aware of what they were perceiving, another potential marker of consciousness.

Invertebrate inner lives?

Another experiment showed that octopuses (Octopus bocki)5, when picking between two chambers, avoided one where they had previously received a painful stimulus in favour of one where they were given an anaesthetic. This suggests that they experience and actively avoid pain, which some researchers think indicates conscious experience.

Day 3 of Fishuary!

Prompt: Wrasse

—

Ignore that I’m. Already behind. Had to choose a wrasse I see almost daily at work!

The blue-streak cleaner wrasse, labroides dimidiatus, my eternally beloved. These little guys are so important! They help out a bunch with our reef tanks, as not only do they keep our rays and fish clean, but they also eat parasites!

These dudes are so smart, they will not return to animals that snap at them while giving them a bath! Fish know better than to eat them as well. They’re our super good little janitors, love them for that. They’ve also been observed recognizing their own reflection; it’s not the best scale of intelligence for animals, but that’s a pretty interesting fact about them! These guys are pretty small as well, about two or three inches long at most, we love that here.
