The humphead wrasse (Cheilinus undulatus) is a large coral fish that has become threatened due to habitat loss and fishing pressure. We sequenced the mitochondrial genome of C. undulatus, using a normal PCR method. The complete mtDNA sequence encoded 13 protein genes, 22 tRNA genes and 2 rRNA genes. It was found to be 16,613 bp in length and had an overall H-strand base compositions of 27.3 for A, 30.9 for C, 16.8 for G, and 25.0% for T.
Cheilinus undulatus (humphead wrasse) is a marine fish distributed widely throughout the tropical Indo-Pacific. It has been listed as vulnerable in the IUCN Red Data Book and in CITES Appendix II four times. Fifteen microsatellite loci were isolated and characterized for this species. The number of alleles ranged from 3 to 15 per locus, and the observed and expected heterozygosity ranged between 0.0323-0.7742 and 0.2597-0.8773, respectively. The polymorphism information content ranged from 0.2353-0.8520.
