Abstract

Cirripedia is a lower crustacean that has an invaluable place in several aspects of intertidal ecology and anti-fouling research. In this study, we present the first mitochondrial genome of Chthamalus malayensis. The complete mitochondrial genome of C. malayensis is a circular molecule of 15,230 bp. In comparison to the pancrustacean ground pattern, the mitochondrial genome of C. malayensis has a deletion of the trnC gene. Phylogenetic analysis based on mitochondrial protein-coding genes showed that C. malayensis clusters with C. antennatus (BP = 98) and is grouped with C. challengeri, Octomeris sp. BKKC-2014, and Notochthamalus scabrosus. Further studies are needed to reveal the specific phylogenic relationships within Cirripedia.
