フグ目魚類の多様性と系統,そして分類(第12回日本動物分類学会奨励賞受賞記念論文)

抄録

The order Tetraodontiformes is regarded as one of the most highly derived groups among teleostean fishes and contains 435 species among 104 genera of 10 families. They have been studied in various academic disciplines such as phylogeny, anatomy, toxicology, fisheries, and genome biology. In this review, I present a series of studies on the phylogeny and taxonomy of tetraodontiform fishes of various taxonomic levels led by me. The studies involved various aspects such as the phylogenetic position and sister group of the order, familial relationships, relationships between balistids and monacanthids and evolution of pelvic elements, phylogeny and timescale of fugu of the genus Takifugu, relationships between tetraodontid fishes and their adaptation process to freshwater, and taxonomy of molids of the genus Mola. The results of these studies proposed evolutionary hypotheses that are largely incongruent with the conventional ones and revealed many problems regarding their taxonomy and classification.
