The Smooth Hammerhead Shark

Описание: The smooth hammerhead shark (Sphyrna zygaena) is a fascinating species with unique biological features that suit its predatory lifestyle in the ocean. Here's an overview of its biology:
Physical Characteristics:
The smooth hammerhead shark gets its name from its distinctively shaped head, known as the "cephalofoil," which is flattened and laterally extended into a hammer-like shape. Unlike some other hammerhead species, the smooth hammerhead's cephalofoil lacks an indentation in the center.
Its body is sleek and streamlined, allowing it to move swiftly and efficiently through the water.
Smooth hammerheads have a counter-shaded coloration, with a dark gray or brownish dorsal surface and a lighter underside. This helps them blend in with their surroundings when viewed from above or below.
Size:
Smooth hammerhead sharks are among the larger species of hammerheads, with adult lengths typically ranging from 10 to 14 feet (3 to 4.3 meters).
They can weigh anywhere from 300 to 500 pounds (136 to 227 kilograms), although larger individuals have been recorded.
Habitat:
Smooth hammerhead sharks are found in warm temperate and tropical waters worldwide. They inhabit both coastal and offshore regions, preferring depths ranging from shallow coastal waters to deeper oceanic zones.
Diet:
As apex predators, smooth hammerhead sharks feed on a variety of prey, including fish, squid, octopus, and occasionally crustaceans.
Their broad, serrated teeth are well-suited for grasping and cutting through the flesh of their prey.
Reproduction:
Smooth hammerhead sharks are viviparous, meaning they give birth to live young rather than laying eggs. The embryos develop within the mother's body, nourished by a placental connection.
After a gestation period of around 9-10 months, the female smooth hammerhead will give birth to a litter of pups, typically numbering between 20 to 40 individuals.
