The complete mitochondrial genome of Haloa japonica (Pilsbry, 1895) (Cephalaspidea, Haminoeidae)

Haloa japonica is a bubble snail species in the family Haminoeidae. In the present study, the complete mitochondrial genome of H. japonica was decoded and analyzed. With the size of 13,797 bp, the mitogenome of H. japonica is the shortest among all known mitogenomes of the order Cephalaspidea. Overall base-pair composition of the mitogenome was 69% A-T and 31% C-G. The phylogenetic tree showed a clade of H. japonica and other species in the family Haminoeidae.
