The complete mitochondrial genome of Amphioplus laevis was 16,084 bp in length (Genbank accession: MN276320). It contained 13 protein-coding genes, 2 ribosomal RNA and 22 transfer RNA. The GC contents of A. laevis was 37.59%. The gene order was similar with species in the same family. Phylogenetic relationships within known ophiuroids reconstructed by 13 protein-coding mitochondrial genes, which showed that it was mostly related to Amphiopholis squamata, corresponding to the gene order. These results could provide a novel insight to the phylogeny of Ophiuroidea.
