摘要: The complete mitochondrial genome of the tawny nurse shark (Nebrius ferrugineus) was first presented in this study. It was 16 693 bp in length with the typical gene order in vertebrates. The overall base composition was 33.6% A, 25.6% C, 12.7% G and 28.1% T. Two start (ATG and GTG) and two stop (TAG and TAA/T--) codons were found in the protein-coding genes. The size of 22 tRNA genes ranged from 67 to 75 bp. The origin of L-strand replication could form a hairpin structure. All nodes strongly supported that N. ferrugineus was placed as sister to Rhincodon typus in the Bayesian tree.
