Abstract
The complete mitochondrial (mt) genome of the Neptune whelk, Neptunea arthritica cumingii, was determined using genome walking techniques in this study. The total length of the mt genome sequence of N. arthritica cumingii was 15 256 bp, including 13 protein-coding genes, 21 transfer RNA genes and 2 ribosomal RNA genes. The overall composition of the mitogenome was estimated to be 30.85% for A, 38.59% for T, 15.15% for C and 15.40% for G, indicating that an A + T (69.44%)-rich feature occurs in the N. arthritica cumingii mitogenome. The phylogenetic relationships of 11 mollusc species were constructed based on the complete mtDNA sequences by the neighbour-joining method using MEGA 5.0 software (MEGA Inc., Englewood, NJ).
Highlights
The Neptune whelk, Neptunea arthritica cumingii, belongs to the family Buccinidae and is delicious with internal fertilization and direct development (Richard et al 2008)

In order to restore and protect the wild N. arthritica cumingii resources, it is necessary to carry out wild resource investigation and germplasm analysis
