How does a great hammerhead shark behave?

The great hammerhead shark (Sphyrna mokarran) is a large and distinctive shark characterized by its unique "hammer-shaped" head. These sharks are known for their bold and curious behavior. Here are some notable traits and behaviors of great hammerhead sharks:

1. Curiosity: Great hammerhead sharks are known for their inquisitive nature. They often approach divers, boats, and other objects in their environment to investigate and assess the situation. This curiosity sometimes leads them into interactions with humans, including close encounters while diving or snorkeling.

2. Group Behavior: Great hammerheads are often seen in schools or groups, particularly when hunting or feeding. They may work cooperatively to locate and capture prey, taking advantage of their numbers to increase their chances of success.

3. Aggressive Feeding: Great hammerheads are apex predators and can exhibit aggressive behavior during feeding. They have a powerful bite and are capable of taking down large prey. When food is scarce, they may become more aggressive and compete fiercely for available resources.

4. Sensory Organs: The unusual head shape of great hammerhead sharks provides them with enhanced sensory capabilities. Their widely spaced eyes on the outer edges of the hammerhead allow for excellent binocular vision, providing depth perception and increased visual coverage of their surroundings. Additionally, their nostrils, located on the underside of the head, may be used for specialized chemical sensing.

5. Reproductive Behavior: Great hammerheads are ovoviviparous, meaning that females retain the fertilized eggs internally and give birth to live young. The gestation period can last several months, after which females may produce litters of up to 50 pups. The newborns are relatively large, typically ranging between 50-70 cm in length.

6. Migration and Long-Distance Movements: Great hammerheads are highly mobile and capable of long-distance movements. They can cover extensive areas in search of prey and suitable habitats. They are found in both coastal and offshore waters, often near coral reefs, continental shelves, and deep water drop-offs.

It's important to note that while great hammerheads may display curious and bold behavior, they are still considered potentially dangerous animals due to their size and power. Interactions with great hammerheads should always be approached with caution and respect for their natural behaviors and habitat.
