Characterization and phylogenetic analysis of the complete mitochondrial genome of Actinopyga lecanora (Jaeger, 1833) (Holothuriida: Holothuriidae)

The white-bottomed sea cucumber, Actinopyga lecanora, is a valuable inshore fisheries resource which is famous for its high nutrition and pharmacological compounds. However, due to morphological plasticity and limited molecular phylogenetic studies, the taxonomic histories in the genus Actinopyga have not been completely resolved yet. Moreover, there remains a complex of cryptic species within Actinopyga, many of which are incorrectly assigned within the family Holothuriidae. In this study, we report the complete mitochondrial genome of A. lecanora. The mitogenome has 15,568 base pairs (63.40% A + T content) and is made up of a total of 37 genes (13 protein-coding, 22 transfer RNAs and 2 ribosomal RNAs), plus a putative control region. This study offers useful mitogenome data for future phylogenetic and taxonomic classification of Holothuriidae.
