smooth hammerhead shark iucnmauritania pronunciation sound

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.
Physically, the mature females have considerably wider uteri than their maturing counterparts. 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. Among the reasons for this drop off are overfishing and the rise in demand for shark fins. We acknowledge that this land and sea was and always will be Aboriginal land and sea. 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. The shape of its head allows it to bury into the seafloor and pin stingrays down. Hammerhead sharks have never been involved in a fatal incident. Scalloped hammerhead sharks are listed under the EPBC Act, the piece of Australian law that governs how we protect endangered wildlife from threats. They are not considered dangerous and are normally not aggressive towards humans. Since 1937 in NSW and 1962 in QLD, lethal shark control programs have been carried out each year using either nets or drumlines. Hammerhead sharks are over fished all around the world for their fins and liver oil. Reproduction is iteroparous, viviparous, and dioecious. It is associated with freshwater habitat. It is estimated that 1.3 to 2.7 million fins are collected each year from smooth and scalloped hammerhead sharks for the shark fin trade.

Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species.

This seemingly protects the interests of commercial fishing at the expense of our environment and wildlife – by allowing continued fishing of threatened species if a plan to manage the capture of the species is in place. 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. This means there is limited information on the actual number of each of these threatened species caught in Australian waters.Commercial fishing is the biggest threat to hammerheads, with 370t of hammerhead sharks legally allowed to be caught every year in Australian waters (1).The trade in these species is regulated by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) convention. In six years (2012-2018), 592 hammerheads sharks have been culled at an average of 99 per year (6). predator and prey. The younger the sharks, the closer to the surface they tend to be, while the adults are found much deeper in the ocean. Many fishery reports have historically only reported the number of ‘hammerheads’ caught, rather than giving the numbers of each species caught. Australia is a signatory to the convention.Any trade of CITES listed species must conform to a Non-Detriment Finding (NDF) which contains management guidelines to ensure the species survival is not threatened by trade. An NDF is a decision and report made by the Federal Government using information provided by an independent and objective scientific assessment of CITES listed species.AMCS questions the findings in the NDF report that the current levels of hammerhead harvest are sustainable and instead recommends a more precautionary approach that restricts catch and prohibits export in light of:Hammerhead sharks are also threatened by culling through lethal shark control programs. It is estimated that 1.3 to 2.7 million fins are collected each year from smooth and scalloped hammerhead sharks for the shark fin trade. It is listed as vulnerable by IUCN and in CITES Appendix II. Under this category, 78 tonnes of hammerhead sharks can be caught in the Great Barrier Reef, the largest catch of the species anywhere around Australia.Great and smooth hammerheads have no protection under the EPBC Act and are not listed to date.By contrast, the IUCN, an international body that assesses the conservation status of wildlife, assessed great and scalloped hammerheads as critically endangered and smooth hammerheads as vulnerable (3, 4). In parts of the Atlantic Ocean, their populations have declined by over 95% in the past 30 years. In six years (2012-2018), 592 hammerheads sharks have been culled at an average of 99 per year (6).Hammerhead sharks have never been involved in a fatal incident. Researchers attribute this growth in demand to the increase in shark fins as an expensive delicacy (such as in Hammerhead sharks are over fished all around the world for their fins and liver oil.

These methods are outdated and ineffective – in 2006 a fatal shark bite occurred on a drumlined beach in Amity Point, QLD (7).The Australian Marine Conservation Society acknowledges the Traditional Custodians of this land and sea country, and pay our respects to their Elders past and present.
