The smooth hammerhead shark, Sphyrna zygaena, boasts a unique T-shaped head aiding in sensory perception and maneuverability. Found in warm-temperate and tropical oceans, this social predator preys on fish and cephalopods. Notably, it's capable of entering brackish waters and exhibits migratory behavior.

Sphyrna zygaena, commonly known as the smooth hammerhead shark, is native to temperate and tropical waters worldwide. These sharks are found in the Atlantic Ocean, ranging from Nova Scotia to Argentina in the western Atlantic, and from the British Isles to South Africa in the eastern Atlantic. They also inhabit the Indian Ocean and the Pacific Ocean, from southern California to Chile in the eastern Pacific, and from Japan to Australia in the western Pacific.

The smooth hammerhead shark typically inhabits coastal waters and continental shelves, often found in depths ranging from 20 to 200 meters, although they can dive to depths of up to 500 meters. They prefer temperate and tropical climates and are often seen in bays, estuaries, and the open ocean.

Sphyrna zygaena is a predatory species that plays a crucial role in marine ecosystems. They feed on a variety of prey, including fish, cephalopods, and crustaceans. Their distinctive head shape allows them to enhance sensory perception and maneuverability, aiding in their role as active predators. Smooth hammerheads may also exhibit migratory behavior, moving to different regions in response to seasonal changes and prey availability.
