Mitochondrial genome of the bull shark Carcharhinus leucas (Carcharhiniformes: Carcharhinidae)

Abstract

The bull shark Carcharhinus leucas is a large elasmobranch species widespread in tropical and warm oceans, rivers and lakes. We first determine the complete mitogenome of C. leucas in this article. It is 16,704 bp in length, consists 37 genes and one control region with the typical gene order in vertebrates. The ND6 gene used the rare AGG as stop codon. The 22 tRNA genes ranged from 67 to 75 bp. The tRNA-Ser2 lacks the dihydrouridine arm and cannot form the typical cloverleaf structure. The control region is 1066 bp in length with high A + T and low G contents.
