Scalloped hammerhead (Sphyrna lewini)

IUCN Red List Status: Endangered

Distinguished by a flattened, laterally expanded head that gives this species is name

One of 10 species of hammerhead sharks!

Elaborate patterns of special sensory organs, Ampullae of Lorenzini, found along the underside of their head allows these sharks to find prey items buried within the sand

Coastal and semioceaniccircumglobal distribution in warm temperate and tropical waters

Particularly vulnerable because all life stages are subject to directed and non-directed fishing capture

Because of high fin ray (the supportive structures in shark fins) numbers, hammerhead fins are highly valued, which has led to increased targeting of this species

It’s been shown, worldwide, that populations segregate by sex, and when mature, females migrate to the coast to have pups

Nursery areas found in shallow inshore areas, while adults are more offshore

Maximum sizes reported up to ~11 feet

This species known for their schooling behavior, where number of individuals can be several hundred at a time
