Carolina hammerhead

Common name: Sphyrna Gilberti

This shark belongs to the hammerhead family, where the head itself is the signature field mark. PocketShark uses that broad sensory platform as the visual anchor, then adds species-specific differences when the source base is stronger.

Smooth hammerhead

Common name: hammerhead

Smooth hammerheads move between coastal and offshore waters, sometimes forming elegant schools when young. Their broad, unnotched hammer sets them apart from more angular relatives. In many regions, their future depends more on fishery management than on public fear.
