Explore a Rare Hammerhead Shark Nursery in the GalapagosExplore a Rare Hammerhead Shark Nursery in the Galapagos The wide head and special sensory cells allows the scalloped hammerhead to successfully detect fishes.The gestation period is reported to be around 12 months.As of 2008, the scalloped hammerhead is on the "globally endangered" species list.
The Scalloped Hammerhead Shark is mostly found on the continental shelves and prefers the deeper waters. They are threatened by commercial fishing, mainly for the shark fin trade.

The scalloped bonnethead (Sphyrna corona) or mallethead shark is a … The fish typically need constant water flow to breathe, so researchers only have two minutes to tag the animal from the time they catch it to the time they must put it back in the water, to ensure its survival.Park rangers in that area of the Galápagos Islands have been monitoring and tagging hundreds of sharks for years, As a result, only the fit… The female will have between four and 42 babies, called pups, which are born alive and able to care for themselves. Scalloped Hammerhead Nursery Explored in the Galapagos Islands Like all sharks, scalloped hammerheads do not care for their young—the sharks are born with everything they need for a predatory life. 2020 National Geographic Partners, LLC. These sharks occupy tertiary trophic levels.Juveniles and pups thrive in shallow coastal waters, such as bays and mangroves, which provide shelter from predators and waters high in nutrients from deposited sediments. Among the reasons for this drop off are overfishing and the rise in demand for shark fins. Like most sharks, parental care is not seen.

They are sensitive to light and because of their enhanced social behavior, these sharks are found closer to shore lines during the day and mostly remain in deep s… They are not considered dangerous and are normally not aggressive towards humans. Compared to other species, the scalloped hammerhead produces large litters, and this is most likely due to high infant mortality. Scalloped hammerhead sharks are moderately large sharks with a global distribution.

In parts of the Atlantic Ocean, their populations have declined by over 95% in the past 30 years. But to give their young something of a head start, hammerheads lay large litters of up to 30 shark pups in particularly habitable coastal areas. Physically, the mature females have considerably wider uteri than their maturing counterparts. Scientists in the Galápagos recently discovered a natural breeding site, or nursery, for scalloped The nursery was discovered along the coast of Santa Cruz Island in November, adding to the archipelago's importance as one of the Scalloped hammerhead sharks are using the sheltered, crustacean-filled mangroves along Santa Cruz Island to breed.
Research carried out by the non-government organisation These sharks are often seen during the night, day, and morning in big schools, sometimes numbering hundreds, most likely because large groups can obtain food easier than singles or small groups, especially larger and trickier prey, as commonly seen. Their natal sites still cause high infant mortality; a lack of resources prevents all the young from surviving. The most distinguishing characteristic of this shark is it's "hammer-shaped" head.

Females give birth to their pups, sometimes in litters of 30 or more, after a nine- to ten-month gestation.The female sharks then leave the young in the well-protected, food-rich environment, where they slowly mature to adulthood, safe from many of their natural predators (like other sharks) in the open ocean.When the scientists tag the sharks they have to work fast. The gestation period is reported to be around 12 months.

Scalloped Bonnethead. © 1996-2015 National Geographic Society, © 2015- Nursery grounds for this species are predictable and repeated over the years, and they are faithful to their natal sites. On average, males measure 1.5 to 1.8 m (4.9 to 5.9 ft) and weigh about 29 kg (64 lb) when they attain sexual maturity, whereas the larger females measure 2.5 m (8.2 ft) and weigh 80 kg (180 lb) on average at sexual maturity.These sharks have a very high metabolic rate, governing behavior in acquiring food. It is found abundantly in depths of 1600 feet (500 meters) and is also often found in shallower waters of about 80 feet (25 meters). A lack of mating scars has been found on mature females.The male-to-female ratio of the scalloped hammerhead is 1:1.29.Scalloped hammerhead sharks have a homing behavior to navigate in the ocean.The scalloped hammerhead uses deep water to survive as safety and feeding.The scalloped hammerhead has a lot of advantages to capture its prey. The younger the sharks, the closer to the surface they tend to be, while the adults are found much deeper in the ocean.
