Neighbor-Joining phylogenetic tree of the cytochrome c oxidase subunit I (COI) gene of the four coral reef fishes from the South China Sea with the maximum composite likelihood and bootstrap method (Q = 1000) was rooted by Ah (Acanthogobius hasta) and Lj (Lampetra japonicum) and constructed with mega 6.0. The clone sequences of the fish were downloaded from NCBI and the locus_tags were KC353468.1, NC_006131.1, MK567523.1, MK658630.1, FJ416614.1, MK566923.1.
