Complete mitochondrial genome of tiger cowrie Cypraea tigris (Linnaeus, 1758)

Abstract

The complete mitochondrial genome of Cypraea tigris from the South China Sea has been determined, which was the first report of complete mitogenome in the superfamily Cypraeoidea. It is 16,177 bp long and consists of 21 tRNA genes, 2 rRNA genes, 13 protein-coding genes (PCGs), and 1 control region. The base composition of C. tigris mitogenome is biased (A, G, T, and C were 28.8, 17.9, 37.1, and 16.3%, respectively) with A + T contents of 58.5%. All of the PCGs use a typical start codon (ATN) and a complete stop codon (TAA or TAG) as normal. The maximum-likelihood tree demonstrated that the Cypraeoidea was closer to the superfamily Tonnoidea, and further clarified the phylogenetic relationships of each superfamily in Littorinimorpha.
