Complete mitochondrial genome and the phylogenetic position of the blackspotted catshark Halaelurus burgeri (Carcharhiniformes: Scyliorhinidae).

ABSTRACT: In this study, the mitogenome of the blackspotted catshark Halaelurus burgeri was first determined. This circle molecular was rich in A (30.7%)+T (30.4%), poor in C (25.0%)+G (13.8%) and contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a longest control region (3481 bp with lots of repeated motifs) in sharks. Two start codons (ATG and GTG) and two stop codons (TAG and TAA/T) were found in the protein-coding genes. The 22 tRNA genes ranged from 66 bp (tRNA-Ser2) to 75 bp (tRNA-Leu1). The phylogenetic result showed that H. burgeri did not cluster to the two species of Scyliorhinidae (Cephaloscyllium umbratile and Scyliorhinus canicula).
