| Research Abstract |
We studied the following theams using cognitive fishes living stable sociality through laboratory experiments, 1) mirror-self-recognition, 2) face recognition, 3) female control of male recognition of paternity, 4) transitive inference, 5) dear enemy effect, so on. Almost all studies were successful. Most were findings for the first time in fish, and indicating that teleost fishes will have much high cognitive abilities than previously regarded, and there will be similarlity in these social cognition pattern to those of higher vertebtaes such social mammals. specially, the similarity of processes in mirror-self-recognition betweem the cleaner fish and mammals are noticeable, and further studies are required.
Recently, neuroethology found the neuronsystem similairty through vertebrates from from fish to mammals. These similarity will be related to or reflect the he similarity of social cognition between these fish and social mammals.
