title: Complete mitochondrial genome and the phylogenetic position of the Blotchy swell shark Cephaloscyllium umbratile.
abstract: In this study, the complete mitochondrial genome of the Blotchy swell shark Cephaloscyllium umbratile was determined. It was a circle molecular (16 698 bp), contained 37 genes with typical order to that of most other vertebrates. The nucleotide composition was 31.0% A, 24.0% C, 14.0% G, and 31.3% T. There were 26 bp short intergenic spaces located in 11 gene junctions and 28 bp overlaps located in 7 gene junctions in the whole mitogenome. Two start codons (GTG and ATG) and two stop codons (TAG and TAA/T) were used in the protein-coding genes. The phylogenetic result showed that C. umbratile was clustered with Scyliorhinus canicula and formed the Scyliorhinidae clade, which was the most basal clade within Carcharhiniformes, and Carcharhinidae is not monophyletic.
