Scalloped hammerhead

Swim, Snorkel, Dive, See, Meet, Watch the Scalloped hammerhead

The Horned Hammerhead Shark will gladly go to a cleaning station to have its skin cleaned of parasites. During the day, these sharks gather in schools in which there is a strong sense of hierarchy, with the dominant animals in the middle of the group. There is a mode of communication between the different congeners in the school. With a size of 4.3 m and weighing more than 150 kg, its head has a hydrodynamic function. It is used as a support to help it turn during its movements. The flatness of his head increases his ability to collect visual and olfactory information thanks to the presence of Lorenzini's bulbs. This device allows him to detect electric fields produced by buried prey, such as stingrays. It has a visual field of 182° and has a good sense of distance evaluation. It can see both above and below it at the same time. This shark is fished for its medicinal qualities. Its flesh is poisonous and full of heavy metals. It only becomes aggressive to divers if they are feeding in the area. It is on the IUCN Red List of Threatened Species in danger of extinction within the next 50 years. There are nine species of hammerhead sharks.

Food

At night, at great depths, the Scalloped hammerhead hunts alone for sardines, herring, juvenile sharks, cephalopods and crabs, shrimp and sea snakes. It locates them with a highly developed sensory system thanks to the shape of its head, which enables it to collect visual and olfactory information. The Scalloped Hammerhead is pelagic and ranges from a few metres below the surface to 250 metres below the surface along the coast. It prefers coral reef flats and drop-offs as well as estuaries and brackish waters.

Breeding

This species is viviparous. The female can stock sperm several months to fertilize the eggs. The gestation period lasts 10 months. The female gives birth to 15 to 38 juveniles. The pups measure 60 cm. They remain in shallow waters, in areas free from predators. The Scalloped hammerhead attains sexual maturity when it reaches a length of around 1.5 to 2m and around the age of 17 depending on whether it is a male or a female. When the mating season begins the male bites the female to latch onto her.

Unexso Diving Center
Bahamas  - Port Lucaya Marina
English

The Underwater Explorers Society (UNEXSO) dive center was established in 1965. Open every day of the year from 8 am to 5 pm. On-site, a 2-story shop, Sun and Sea Outfitters, is stocked with diving equipment and holiday clothing. After a great day of diving, relax by the pool at the Dive In Marina Bar & Restaurant and sit down to a Bahamian meal or... a cheeseburger! Step back in time with a visit to the Dive Museum, featuring diving artifacts from UNEXSO's inception in 1965. Board one of the 7 Unexso boats for half or full-day trips with equipment rental and nitrox filling. Whether you are an experienced diver or a beginner, a family or a honeymooner, you will find a team of professional diving instructors on-site! You don't have to dive or snorkel to see the spotted or long nose dolphins in their environment. Even non-divers have the chance to interact with these incredible animals by swimming alongside them. Because swimming with dolphins is a Bahamian island-specific activity! Meet them in the waters of Orange Cay, or in the freshwater river that divides Andros Island. When you go out to meet wild dolphins, there is no guarantee that they will cooperate. With the Dolphin Swim, divers swim with dolphins in the protected waters of Sanctuary Bay. With the Dolphin Close Encounter program, you can sit on a partially submerged platform and spend time with the dolphins. UNEXSO also offers a half-day dolphin assistant training course (minimum age 16) to learn more about dolphin care. You then buy your photo! Also explore the popular wrecks Theo, Sea Star, and Rose that Unexso helped sink in the waters of Gran Bahamas. Explore some of the best sites in the Bahamas with Unexso such as Shark Junction, Theo's Wreck, Dolphin Dive, and Deep reefs. [+]
