title: Complete mitochondrial genome and phylogenic analysis of the mudskipper Scartelaos gigas (Perciformes, Gobiidae).
abstract: In this paper, the complete mitochondrial genome sequence of Scartelaos gigas was firstly determined. The circular genome (16 717 bp) comprises 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 1 control region. The overall base composition of S. gigas is 28.9% for C, 28.3% for A, 26.4% for T, 16.4% for G, with a slight A + T bias of 54.7%. In the control region, the termination-associated sequence and conserved sequence block domains were found, but the tandem repeat structure was not found. It has the typical vertebrate mitochondrial gene arrangement. The phylogenic analysis using the Neighbor-Joining method showed that the fishes belonging to Gobiidae, Odontoburidae, and Eleotridae formed three branches grouped with other fishes into one clade which separated from the mammals. We hope that the results from the present study will provide useful molecular information for the further studies on genetic structure and demographic history of S. gigas.
