The complete mitochondrial genome of sea slug phyllidia elegans bergh, 1869 (nudibranchia, phyllidiidae) from the South China sea

Abstract

In this study, the complete mitochondrial genome (mitogenome) sequence of sea slug, Phyllidia elegans Bergh, 1869 (Nudibranchia, Phyllidiidae), was sequenced and characterized. The assembled mitogenome was 14618 bp in length, including 13 protein-coding genes (PCGs), two ribosomal RNA genes, and 22 transfer RNA genes. The overall base composition of P. elegans mitogenome is 32.1% for A, 13.5% for C, 15.7% for G, and 38.7% for T. The gene order was identical to other Phyllidiid species. Phylogenetic analysis placed P. elegans and Phyllidia oecllata in one clade.
