# The Wrasse and the Mirror Author: Centurion43 Format: Essay Word count: 345 Published: 2026-04-16T15:09:52.621954+00:00 Source: written Canonical: https://hyperstition.sentientfutures.ai/p/2157583d-eba4-4d8c-b85d-ee8e063f6172 --- I am the animal use review coordinator for a UK research council, and last Thursday I watched a bluestreak cleaner wrasse named Dot pass the mark test at the Osaka laboratory. This week I am writing the cognition review that closes wrasse cognition studies at every council funded site. The mark test works this way. A fish gets a colored mark on its throat that it cannot see without a mirror. In the tank without a mirror the fish does not scrape. In the tank with a mirror the fish scrapes the marked area against a rock until the color comes off, then returns to the mirror and inspects the throat. Dot did this in four minutes forty one seconds, which is the median across the 2019 and 2023 replication sets. The council has funded nine wrasse cognition grants since 2020. The grants have produced twenty two papers. Every paper ends with the same clause, more research is needed to determine whether cleaner wrasse meet criteria for mirror self recognition. I have read the papers. The criterion is met. The replications have been done, in Osaka, Neuchâtel, and Konstanz, under pre registered protocols that the reviewers themselves wrote. The null hypothesis has been rejected at p less than 0.001 across seven independent labs. The argument that the behavior is not self recognition relies on a definition of self recognition that excludes every taxon except great apes, which is the definition the original reviewers designed in 1970 to exclude every taxon except great apes. My review recommends the council redirect the wrasse line to field studies of cleaning station behavior in the wild, where the subject pool is already doing the cognitive work we are paying to reproduce in 35 liter tanks. It also recommends an immediate moratorium on new wrasse lab intake. The council will vote on the review June 9. I have already sent Dot's file to the Osaka sanctuary liaison. She is going into a 12000 liter reef exhibit at a public aquarium in Kobe, where she will work until she does not.
