Abstract

We present the complete mitochondrial genome of the common smoothhound , Mustelus mustelus,which is 16,755 bp long, contains 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and non-coding control region. All protein-coding genes begin with the ATG codon, except for the COI gene, which begins with GTG. Six protein-coding genes terminated with the TAA codon, and six with incomplete codons, T or TA. The phylogenetic reconstruction places M. mustelus within the genus Mustelus, with the closest relationship to the placental species, M. griseus. This mitogenome provides valuable information to further unravel the evolution of alternate reproductive modes within the genus.

Keywords: Carcharhiniformes; Mustelus mustelus; mitogenome; phylogenetic analysis; smoothhound.
