Abstract
The mitogenome of the Greytail angelfish Chaetodontoplus poliourus (Pomacanthidae) was decoded using next-generation sequencing techniques. The de novo assembled mitogenome consists of 16,961 bp, including 13 protein-coding genes, 2 ribosomal RNAs and 22 transfer RNA genes. The gene arrangement is identical to the other available Pomacanthidae mitogenomes submitted to NCBI. The overall base composition of the C. poliourus mitogenome was estimated to be 28.0% A, 30.9% C, 15.8% G and 25.3% T. The phylogenetic analysis of the C. poliourus mitogenome suggests a closer genetic relationship with Vermiculated angelfish Chaetodontoplus mesoleucus as expected from their similar color patterns. The overall pairwise identity except D-loop is 93.7% for these two sister species. The decoding of the C. poliourus mitogenome has enriched gene database for further evolutionary studies and conservation assessments of this uncommon and newly described marine angelfish.
