Abstract:
The complete mitochondrial genome of the Sicklefin weasel shark Hemigaleus microstoma was first presented in this study. It was 16 701 bp in length with the typical gene arrangement in vertebrates. A total of 25 bp short intergenic spaces and 33 bp overlaps located in 12 and 9 gene junctions, respectively. The overall nucleotide composition was 31.0% A, 26.4% C, 13.5% G and 29.1% T. Two start (ATG and GTG) and three stop (TAG, AGG and TAA/T) codons were found in the protein-coding genes. The size of 22 tRNA genes ranged from 67 to 75 bp. In the phylogenetic tree, H. microstoma (Hemigaleidae) was placed as sister to Galeocerdo cuvier (Carcharhinidae).
