Abstract

In this study, we sequenced the circular mitochondrial genome (mitogenome) of Cercodemas anceps. This genome was determined to measure 16,539 bp in length and contain 13 protein-coding genes (PCGs), 22 tRNA genes, and 2 rRNA genes. The longest gene was observed to be nad5, which measures 1,641 bp in length and is located at position 6,540 ∼ 8,180 of the C. anceps mitogenome. One PCG, nad6, and five tRNA genes (tRNASer(UCN) , tRNAGln , tRNAAla , tRNAVal, and tRNAAsp ) were located on the light chain, and the other genes were located on the heavy chain. A phylogenetic tree was constructed with the mitogenome sequences of 26 types of echinoderm species, and the results show that C. anceps is most closely related to C. quadrangularis.
