Molecular analyses reveal a lack of genetic structuring in the scalloped hammerhead shark, Sphyrna lewini (Griffith & Smith, 1834) along the Indian coast
The scalloped hammerhead shark, Sphyrna lewini (Griffith and Smith, 1834), is an important species along the Indian coast both in the Arabian Sea and Bay of Bengal. As per the IUCN Red List Assessment, the scalloped hammerhead shark is categorized as “globally endangered.” We investigated the intra-...

As per the IUCN Red List Assessment, the scalloped hammerhead shark is categorized as “globally endangered.” We investigated the intra-specific genetic diversity and population genetic structure of
