First record of the complete mitochondrial genome of the mantis shrimp, Gonodactylaceus randalli (Manning, 1978) (Stomatopoda: Gonodactylidae)

Biofouling has long been known as a major route for the invasion by non-indigenous species. The mantis shrimp, Gonodactylaceus randalli, is the first stomatopod species that has been identified in a biofouling community. In this study, we sequenced and analyzed the complete mitochondrial genome sequence of this species for the first time. Its mitochondrial genome is 15,907 bp in length and comprises 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and a non-coding A + T-rich region. The overall base composition in the heavy strand is as follows: A: 37.3%, T: 31.3%, G: 11.9%, and C: 19.4%, with a G + C content of 31.3%. The phylogenetic analysis revealed that G. randalli belonged to the families Protosquillidae, Gonodactylidae, and Takuidae, in the same clade, within the superfamily Gonodactyloidea. This is the first record of the complete mitochondrial genome sequence of the genus Gonodactylaceus.
