The complete mitochondrial genome of the Japanese mud shrimp Upogebia major (Crustacea, Decapoda)

We determined a full-length sequence of mitochondrial (mt) genome from Upogebia major. This is the first complete mt genome report for infraorder Thalassinidea in Decapoda, Crustacea. Our result showed that U. major generally followed a typical pancrustacean gene order but some tRNA genes showed a very unique gene arrangement such as duplication or translocation. Since none of the complete mt genome sequences in the infraorder Thalassinidea are available yet, this report will provide additional information in relation to mt genome diversity and evolution of the decapods.
