The complete mitochondrial genome of Chinese endemic specie Phascolosoma esculenta (Sipuncula, Phascolosomatidae) from Beibu Bay

摘要

Phascolosoma esculenta is economic important species in the fishery and aquaculture in southeast China. However, whether P. esculenta is conservative endemic specie or a complex of cryptic forms had not been verified yet. Here, we report the complete mitochondrial genome sequence of P. esculenta from Beibu Bay. The mitogenome has 15,494 base pairs and made up of total of 38 genes (13 protein-coding, 23 transfer RNAs, and 2 ribosomal RNAs), and a putative control region. There were only 56 mutations sites within Chinese populations. This study adds second mitogenome of P. esculenta , and will provide useful genetic information for future conservation and exploitation of this economic valuable marine benthic invertebrate.
