Abstract:
The hammerhead shark (Sphyrna zygaena) is listed as a "Vulnerable" species for the International Union for Conservation of Nature (IUCN). Here we report the complete sequence for the mitochondrial genome of the hammerhead shark of a specimen collected from the eastern Pacific Ocean. The genome structure is quite similar to other reported mtDNA shark species. It has a total length of 16,731 base pairs (bp); the base composition was A (31.54%), T (30.23%) C (25.03%) and G: 13.20, contains 13 protein-coding genes, 2 rRNA genes; 21 tRNA genes. In addition, most of the starting (ATG) and ending codons (TAA) for the mtDNA gene regions were registered.
