A hammerhead shark in shallow water. According to the International Shark Attack File, humans have been subjects of 17 documented, unprovoked attacks by hammerhead sharks within the genus Sphyrna since AD 1580. No human fatalities have been recorded. [34] Most hammerhead shark species are too small to inflict serious damage to humans. [8]
The basking shark, a harmless plankton feeder, visits the island in large groups during the winter, but is rarely seen. The common smooth-hound comes close to shore in the late summer to breed, but is too small to be dangerous to humans. [6] The hammerhead shark (Sphyrna zygaena) is another fish eater, and is sometimes encountered while fishing.
Great hammerhead embryos are connected to their mother by a placenta during gestation. As with other hammerhead sharks, great hammerheads are viviparous; once the developing young use up their supply of yolk, the yolk sac is transformed into a structure analogous to a mammalian placenta. Unlike most other sharks, which mate on or near the sea ...

The smooth hammerhead (Sphyrna zygaena) is a species of hammerhead shark, and part of the family Sphyrnidae.This species is named "smooth hammerhead" because of the distinctive shape of the head, which is flattened and laterally extended into a hammer shape (called the "cephalofoil"), without an indentation in the middle of the front margin (hence "smooth").
Hammerhead sharks are overfished all around the world for their fins and liver oil. As of 2020 an estimated 1.3 to 2.7 million fins are collected each year from smooth and scalloped hammerhead sharks for the shark-fin trade. [34] DNA barcoding can assist in the identification of scalloped hammerhead remains to aid conservation efforts. [35]
