The complete mitochondrial genome of the cryptic species (Form II) in kuruma shrimp Marsupenaeus japonicus (Decapoda: Penaeidae)

Abstract

The Kuruma shrimp M. japonicus is economic important species in the shrimp fishery and aquaculture. However, it is a species complex consisting of two cryptic species (Form I and Form II), which can be difficult to identify based on morphology. Here, we report the complete mitochondrial genome sequence of M. japonicus (Form II) from Beibu Bay. The mitogenome has 15,966 base pairs and made up of total of 37 genes (13 protein-coding, 22 transfer RNAs and 2 ribosomal RNAs), and a putative control region. There were 1029 mutations sites between these two cryptic species, and the most variable sites were putative control region. This study adds a distinct mitogenome of M. japonicus (Form II) and will provide useful genetic information for future genetic variation identification and genetic diversity evaluation of this economic valuable shrimp.
