How is the behavior of a hammerhead shark?

Hammerhead sharks are one of the most recognizable sharks in the world, largely because of their hammerhead. The eyes of these sharks are on opposite sides of the head, which allows them to have a wider vision than other sharks. There are nine species of hammerhead shark and these sharks, which belong to the genus Sphyrna, have similar behavioral characteristics.

Migration
During the summer, large schools of hammerhead sharks will migrate to find waters with cooler temperatures. Hammerhead sharks also retreat to warmer waters in winter. They live in marine water environments with tropical climates throughout the world, including the Indian Ocean, the Atlantic Ocean, the Pacific Ocean and the Mediterranean Sea. These sharks are seen near the coasts and offshore. In United States waters, hammerhead sharks generally live near the coasts of southern California, Texas, Louisiana, Mississippi, Florida, Georgia and the Carolinas.

Hunting
Similar to other shark species, hammerhead sharks are carnivores, meaning they only eat meat. When they hunt they use sensory organs, known as the Lorenzini ampule and the lateral lines. The Lorenzini ampule detects electrical fields created by other animals, while the lateral lines detect the movements of other animals. One of the most common elements of the diet of hammerhead sharks are rays; Hammerhead sharks also feed on the barbs of a line’s tail. Fish, invertebrates and other sharks are also a part of the diet of a hammer. Mostly they have small mouths that adapt to eat smaller animals; for that reason they are rarely aggressive towards human beings. However, the larger hammer species, such as the big hammer, sometimes attack humans.

Reproduction
For reproduction, hammerhead sharks are oviparous, which means they lay eggs instead of calving. These sharks mate in spring and summer. The males engage with the females with their intermittent organs, also known as cláspers. The classics release the sperm in the female, which initiates the process of internal fertilization. Hammerhead sharks have a gestation period of 11 months and approximately 30 to 40 young sharks are born annually. Although most sharks mate near the bottom of the ocean, hammerhead sharks swim gradually to the surface of the water during the process.

Social behavior
Hammerhead sharks gather in large schools for hunting, migration and for social purposes. For example, a school of scalloped hammerhead sharks may have 100 to 500 specimens; however, most hammerhead sharks in a school are female. For communication, hammerhead sharks use body language to establish social hierarchy and give orders to schools to disperse. Shaking the head, pushing the torso and swimming in loops are some of the body language cues used by hammerhead sharks. They are also nocturnal, which means they are more active at night.
