| Outline of Final Research Achievements |
The extremely paedomorphic fish Schindleria (Gobioidei, Schindleriidae) includes one of the smallest and youngest reproducing vertebrates and is broadly distributed in the Indo-Pacific Oceans inhabiting coral reef lagoons. This study aimed to elucidate the evolutionary process of this tiny fish, by applying whole mitochondrial DNA (mtDNA) and three nuclear DNA genes sequencing, supermatrix analysis, divergence time and speciation rate estimations, and its ancestral habitat reconstruction. My results suggested that Schindleria was diverged from Oxymetopon at 30 Mya. Phylorate plots for speciation using the gobioid phylogeny showed that the speciation rate of Schindleria was not higher acceleration than the mean rate of all gobioids.
