Complete mitochondrial genome of the tiger shark Galeocerdo cuvier (Carcharhiniformes: Carcharhinidae).

The tiger shark Galeocerdo cuvier is the only member of the genus Galeocerdo. The complete mitochondrial genome of G. cuvier is presented for the first time in this study. The gene composition and arrangement in the mitogenome of G. cuvier is identical to most animal mitogenome. There are 22 bp short noncoding sequences and 44 bp overlaps in the mitogenome. The overall base composition is 31.8% A, 23.9% C, 13.0% G and 31.3% T. The dihydrouridine arm of tRNA-Ser2 was replaced by a simple loop and the other tRNAs could be folded into the typical cloverleaf structure.
