Therefore, the great white shark can be considered an endothermic poikilotherm or mesotherm because its body temperature is not constant but is internally regulated. [69] Groups of dolphins have occasionally been observed defending themselves from sharks with mobbing behaviour. [4][6] According to a 2014 study, the lifespan of great white sharks is estimated to be as long as 70 years or more, well above previous estimates,[7] making it one of the longest lived cartilaginous fishes currently known. From above, the darker shade blends with the sea and from below it exposes a minimal silhouette against the sunlight. [40], Tracing beyond C. hastalis, another prevailing hypothesis proposes that the great white and mako lineages shared a common ancestor in a primitive mako-like species. Up to eight sharks were observed feeding simultaneously, bumping into each other without showing any signs of aggression; on one occasion a shark accidentally bit the head of a neighbouring shark, leaving two teeth embedded, but both continued to feed unperturbed. tuna, rays, other sharks),[108] cetaceans (i.e., dolphins, porpoises, whales), pinnipeds (e.g. [169] Barnett described opposition as "ludicrous" and "extreme", and said that nothing could change his mind. [160] In Queensland, great white sharks found alive on the drum lines are shot. [105] In 2008, a team of scientists led by Stephen Wroe conducted an experiment to determine the great white shark's jaw power and findings indicated that a specimen massing 3,324kg (7,328lb) could exert a bite force of 18,216 newtons (4,095lbf). The iris of the eye is a deep blue instead of black. Shortfin Mako Shark This is the most common of the sharks that can be spotted in the Canary Islands. When members of different clans meet, they establish social rank nonviolently through any of a variety of interactions. [68] For decades, many ichthyological works, as well as the Guinness Book of World Records, listed two great white sharks as the largest individuals: In the 1870s, a 10.9m (36ft) great white captured in southern Australian waters, near Port Fairy, and an 11.3m (37ft) shark trapped in a herring weir in New Brunswick, Canada, in the 1930s. 71. [157], Humans are not appropriate prey because the shark's digestion is too slow to cope with a human's high ratio of bone to muscle and fat. [203], Presently, human-caused shark mortality is continuing, primarily from accidental and illegal catching in commercial and recreational fishing as well as from being caught in beach protection netting, and the populations of great white shark in Australia are yet to recover. The prefix carchar- is derived from (krkharos), which means "jagged" or "sharp". [26] By the 1810s, it was recognized that the shark should be placed in a new genus, but it was not until 1838 when Sir Andrew Smith coined the name Carcharodon as the new genus. Another possibility is that white sharks bite to show their dominance. With Christopher Lowe, Bill Nighy, William Winram. After initially feeding on the whale caudal peduncle and fluke, the sharks would investigate the carcass by slowly swimming around it and mouthing several parts before selecting a blubber-rich area. Answer 1 of 11: Hi All This is probably going to sound really stupid are there sharks in the sea? [31] This was proven with the discovery of a transitional species that connected the great white to an unserrated shark known as Carcharodon hastalis. [17], The novel Jaws by Peter Benchley and its subsequent film adaptation by Steven Spielberg depicted the great white shark as a ferocious man-eater. Great whites are known to have a propensity for "self-healing and avoiding age-related ailments". Most scientists prefer white shark, due to the fact the name "lesser white shark" is no longer used. Unusually for the area, large numbers of sharks over five metres long were observed, suggesting that the largest sharks change their behaviour to search for whales as they lose the manoeuvrability required to hunt seals. Includes: Insurance. Using cameras and footage of seals in aquariums as models and mounted cameras moving at the same speed and angle as a cruising great white shark looking up at the surface from below, the experiment suggests that the sharks are likely colorblind and cannot see in fine enough detail to determine whether the silhouette above them is a pinniped or a swimming human, potentially vindicating the hypothesis. They have bumped or knocked people overboard, usually biting the boat from the stern. Shark Explorers offers uniquely customized shark diving, viewing, and filming expeditions. In August 1981, a great white survived for 16 days at SeaWorld San Diego before being released. White sharks are generally very curious animals, display intelligence and may also turn to socializing if the situation demands it. [31][32] These sharks were considerably larger in size, with megalodon attaining an estimated length of up to 14.216m (4752ft). No accurate global population numbers are available, but the great white shark is now considered vulnerable. [35][36] This transitional species, which was named Carcharodon hubbelli in 2012, demonstrated a mosaic of evolutionary transitions between the great white and C. hastalis, namely the gradual appearance of serrations,[35] in a span of between 8 to 5 million years ago. [55], The great white shark has a robust, large, conical snout. [103], Toxicity from heavy metals seems to have little negative effects on great white sharks. The policy, colloquially referred to as the Western Australian shark cull, was intended to protect users of the marine environment from shark bite incidents, following the deaths of seven people on the Western Australian coastline in the years 20102013. The unborn sharks participate in oophagy, in which they feed on ova produced by the mother. The study reveals the forces and behaviours its skull is adapted to handle and resolves competing theories about its feeding behaviour. While the Monterey Bay Aquarium has been keeping live great white sharks for short periods in their facilities, their 2004-2009 study is the most famous. [45] Juvenile great white sharks inhabit a more narrow band of temperatures (between 14 and 24C (57 and 75F)) in shallow coastal nurseries. Great white shark swimming. Whether or not mortality rates in great white sharks have declined, or the population has increased as a result of the protection of this species in Australian waters is as yet unknown due to the slow growth rates of this species. On the journey out, they swim slowly and dive down to around 900m (3,000ft). This behaviour has also been seen in at least one group of blacktip reef sharks, but this might be learned from interaction with humans (it is theorized that the shark may also be able to smell better this way because smell travels through air faster than through water). They are the must-see sharks of Guadalupe island, each wit. [118] They have also been observed chasing prey after a missed attack. [108], Off California, sharks immobilize northern elephant seals (Mirounga angustirostris) with a large bite to the hindquarters (which is the main source of the seal's mobility) and wait for the seal to bleed to death. However, this has rarely been observed due to whales dying in remote areas. [149] After both attacks, the local population of about 100 great whites vanished. They may not be anywhere near the Islands, but they sure do pass through Cape Verde and the Canary Islands from quite a distance away. Known as the largest predatory fish on the planet, they can grow up to 20 feet and weigh a whopping 5,000 pounds. [107], The great white shark is one of only a few sharks known to regularly lift its head above the sea surface to gaze at other objects such as prey. The species appears to not like the taste of humans, or at least finds the taste unfamiliar. [62] Among living cartilaginous fish, only the whale shark (Rhincodon typus), the basking shark (Cetorhinus maximus) and the giant manta ray (Manta birostris), in that order, are on average larger and heavier. Papastamatiou Yannis P., Mourier Johann, TinHan Thomas, Luongo Sarah, Hosoki Seiko, Santana-Morales Omar and Hoyos-Padilla Mauricio. [26], Molecular clock studies published between 1988 and 2002 determined the closest living relative of the great white to be the mako sharks of the genus Isurus, which diverged some time between 60 to 43 million years ago. One of its earliest mentions in literature as a distinct type of animal appears in Pierre Belon's 1553 book De aquatilibus duo, cum eiconibus ad vivam ipsorum effigiem quoad ejus fieri potuit, ad amplissimum cardinalem Castilioneum. [186], Due to the vast amounts of resources required and the subsequent cost to keep a great white shark alive in captivity, their dietary preferences, size, migratory nature, and the stress of capture and containment, permanent exhibition of a great white shark is likely to be unfeasible.[187]. "White shark" redirects here. [27], There have been a few attempts to describe and classify the great white before Linnaeus. [164] The government of New South Wales also kills great white sharks in its "shark control" program. Open now. As data from captive great whites were no longer needed, the institute has instead shifted its focus to study wild sharks. These sharks grow slowly and take considerable time to mature and produce offspring. Operators in South Africa and Australia continue to use hang baits and pinniped decoys. Humans, for the most part, are too bony for their liking. Because the behaviour is unpredictable, it is very hard to document. Examinations of vertebral growth ring count gave a maximum male age of 73 years and a maximum female age of 40 years for the specimens studied. This page was last edited on 4 January 2023, at 17:41. At present, hang baits are illegal off Isla Guadalupe and reputable dive operators do not use them. [104], A 2007 study from the University of New South Wales in Sydney, Australia, used CT scans of a shark's skull and computer models to measure the shark's maximum bite force. [124], White sharks also attack dolphins and porpoises from above, behind or below to avoid being detected by their echolocation. [178] His first meal as a captive was a large salmon steak on 8 September 2006, and as of that date, he was estimated to be 1.72m (68in) in length and to weigh approximately 47kg (104lb). Harpooned by charter captain John Sweetman, towed boat 30 miles before breaking free. [165], KwaZulu-Natal (an area of South Africa) also has a "shark control" program that kills great white sharks and other marine life. [120][121] Most commonly though, juvenile elephant seals are the most frequently eaten at elephant seal colonies. The findings indicated that estimations by P.Resiley and J.Abela are reasonable and could not be ruled out. Over 12 years old. ", "Great white shark 'slammed' and killed by a pod of killer whales in South Australia", "Killer whales have been killing great white sharks in Cape waters", "Killer whales redistribute white shark foraging pressure on seals", "Incredible Footage Reveals Orcas Chasing Off The Ocean's Most Terrifying Predator", "A shark's eye view: testing the 'mistaken identity theory' behind shark bites on humans", "ISAF Statistics for Worldwide Unprovoked White Shark Attacks Since 1990", "Decline of coastal apex shark populations over the past half century", "Heartbreaking Photos Show the Brutal Lengths Australia Is Going to In Order to 'Keep Sharks Away From Tourists', "Greg Hunt grants WA exemption for shark cull plan", "Can governments protect people from killer sharks? [194] One compromise is to only use chum in areas where whites actively patrol anyway, well away from human leisure areas. Biggest great white sharks are also heavy-bodied, with adults weighing about 1,151 - 1,700 lb (522-771 kg) on average. Prey is usually attacked at the surface. Bullet, Lucy, Scarboard, and Zapata are four great white sharks who have reached superstar status. Possibilities include seasonal feeding or mating. However, the great white sharks off the U.S. West Coast are an isolated population that reside off California and also include individuals off Guadalupe Island, located 150 miles off the west . [119] Shark attacks occur most often in the morning, within two hours of sunrise, when visibility is poor. In fact, the social structure of a clan is probably most aptly compared to that of a wolf pack; in that each member has a clearly established rank and each clan has an alpha leader. [140] The great white has an 11-month gestation period. Though rumours have stated this shark was exaggerated in size or non-existent altogether, witness accounts by the then young Craig Anthony Ferreira, a notable shark expert in South Africa, and his father indicate an unusually large animal of considerable size and power (though it remains uncertain just how massive the shark was as it escaped capture each time it was hooked). [47], The great white is an epipelagic fish, observed mostly in the presence of rich game, such as fur seals (Arctocephalus ssp. [64] A great white shark was captured near Kangaroo Island in Australia on 1 April 1987. In the 1980s, John McCosker, chair of aquatic biology at the California Academy of Sciences, noted that divers who dived solo and were bitten by great whites were generally at least partially consumed, while divers who followed the buddy system were generally rescued by their companion. [172] In a few cases they have bitten boats up to 10m (33ft) in length. Another juvenile female was captured near Malibu on 12 August 2009, introduced to the Outer Bay exhibit on 26 August 2009, and was successfully released into the wild on 4 November 2009. [66], This shark's behaviour and social structure are complex. [76], One contender in maximum size among the predatory sharks is the tiger shark (Galeocerdo cuvier). The crew were undertaking a population study using sardines as bait, and the incident was judged not to be an attack on the boat but an accident. The ocean here was full of sealife. Publicado en marzo 21, 2022 por marzo 21, 2022 por not going diving or anything, prob just snorkelling so not too far off the shoreline?? [125] An incident was documented on 4 October 1997, in the Farallon Islands off California in the United States. [162], Great white sharks are currently killed in both Queensland and New South Wales in "shark control" (shark culling) programs. [25] Another reason might be that "white shark" was a term historically used to describe the oceanic white-tipped shark, and thus, being much larger than the latter shark, it was named "Great" as the "white" part of its name was already used for another shark, which was subsequently referred to as the "lesser white shark". Great White Shark: Directed by Luke Cresswell, Steve McNicholas, David Newton. [135][136], Great white sharks were previously thought to reach sexual maturity at around 15 years of age, but are now believed to take far longer; male great white sharks reach sexual maturity at age 26, while females take 33 years to reach sexual maturity. An estimated 4.75.3m (1517ft) female orca immobilized an estimated 34m (9.813.1ft) great white shark. Females are generally larger than males of this species. [62], A number of very large unconfirmed great white shark specimens have been recorded. Delivery is in spring and summer. The great white shark, however, is rarely an object of commercial fishing, although its flesh is considered valuable. [61][77][78] Some other macropredatory sharks such as the Greenland shark (Somniosus microcephalus) and the Pacific sleeper shark (S. pacificus) are also reported to rival these sharks in length (but probably weigh a bit less since they are more slender in build than a great white) in exceptional cases. [49], In the Northwest Atlantic, the white shark populations off the New England coast were nearly eradicated due to over-fishing. ", "Harpooned Shark Pulls Fishing Boat 14 Hours Off L.I. More than any documented bite incident, Peter Benchley's best-selling novel Jaws and the subsequent 1975 film adaptation directed by Steven Spielberg provided the great white shark with the image of being a "man-eater" in the public mind. Many of the incidents seemed to be "test-bites". In August 1989, a 1.8m (5.9ft) juvenile male pygmy sperm whale (Kogia breviceps) was found stranded in central California with a bite mark on its caudal peduncle from a great white shark. The incident is the first known documentation of great whites actively killing a large baleen whale. [130] In 2020, marine biologists Sasha Dines and Enrico Gennari published a documented incident in the journal Marine and Freshwater Research of a group of great white sharks exhibiting pack-like behaviour, successfully attacking and killing a live juvenile 7m (23ft) humpback whale. [129] According to the testimony of fisherman Dick Ledgerwood, who observed two great white sharks mating in the area near Port Chalmers and Otago Harbor, in New Zealand, it is theorized that great white sharks mate in shallow water away from feeding areas and continually roll belly to belly during copulation. Scuba & Snorkelling Shark Diving. Juvenile white sharks mainly eat bottom fish, smaller sharks and rays, and schooling fish and squids. These observations argue against traditional theories that white sharks are coastal territorial predators, and open up the possibility of interaction between shark populations that were previously thought to have been discrete. Caleton Blanco is a string of small, very similar beaches, with the largest and most popular one bearing the same name. Only sharks that are willing to scavenge follow the chum trail and if they find no food at the end then the shark soon swims off and does not associate chum with a meal. [170] This policy was met with widespread condemnation from the scientific community, which showed that species responsible for bite incidents were notoriously hard to identify, that the drum lines failed to capture white sharks, as intended, and that the government also failed to show any correlation between their drum line policy and a decrease in shark bite incidents in the region. When conserving energy, the core body temperature can drop to match the surroundings. [142], A breach is the result of a high-speed approach to the surface with the resulting momentum taking the shark partially or completely clear of the water. A similar study tracked a different great white shark from South Africa swimming to Australia's northwestern coast and back, a journey of 20,000km (12,000mi; 11,000nmi) in under nine months. Producer and director Jeff Kurr said: "Great White Open Ocean is a film that follows the story of a friend of mine,. [69] Thus, a team of scientistsH. He grew to 1.8m (5.9ft) and 64kg (141lb) before release. When they are born, Great White Shark pups will measure around 5 feet (1.5 meters) and weigh about 77 pounds (35 kilograms). Drone footage shows the jaw-dropping moment a huge great white shark comes within several feet of a child on a surf board. Shark expert Peter Klimley used a rod-and-reel rig and trolled carcasses of a seal, a pig, and a sheep from his boat in the South Farallons. This shark was also estimated to be around 7.13m (23.4ft) long by John Abela and has been designated as MALTA. The Great White Shark is a large lamniform shark that can swim in water as shallow as 3 feet deep.They reach a length of 20 feet (6m) and weigh up to 5,000 pounds (2,240kg). [60][65][66][67] This specimen was reportedly 6.4m (21ft) long and had a body mass estimated at 3,324kg (7,328lb). [108] In 2022, research in South Africa suggested that the great white shark has the ability to change colours to camouflage itself depending on the hormones it gives off. [21] [6] Adults of this species weigh 522771kg (1,1511,700lb) on average;[61] however, mature females can have an average mass of 6801,110kg (1,5002,450lb). A stock image shows a great white shark, unrelated to the one filmed by Alex Higley, whose drone footage shows a close encounter between two dolphins and a trio of sharks. White sharks rarely resort to combat although some individuals have been found with bite marks that match those of other white sharks. Humans' ability to move out of reach with the help of others, thus foiling the attack, is unusual for a great white's prey. Sharks that sink faster during drift dives were revealed to use up their internal stores of energy quicker than those which sink in a dive at more leisurely rates. These three species are generally quite docile in disposition and given to passively filter-feeding on very small organisms. One of these adaptations is a "rete mirabile" (Latin for "wonderful net"). This is a hunting technique employed by great white sharks whilst hunting seals. [69] Another great white shark was caught in Malta by Alfredo Cutajar on 16 April 1987. Known as the "Cojimar Specimen", it allegedly weighed 7,000 pounds (3,175 kg) and was 21 feet (6.4 meters) in length. By ricardomS1214KF. For example, the government of Queensland has a "shark control" program (shark culling) which kills great white sharks (as well as other marine life) using shark nets and drum lines with baited hooks. forklift weight capacity kg lanzarote great white shark. The great white shark is an apex predator, as it has no known natural predators other than, on very rare occasions, the orca. On arrival, he was 1.4m (4.6ft) long and weighed 30.6kg (67lb). Monterey Bay Aquarium in California - 198 Days in Captivity! [9] Great white sharks can swim at speeds of 25km/h (16mph)[10] for short bursts and to depths of 1,200m (3,900ft). [13][14], The species faces numerous ecological challenges which has resulted in international protection. The size, feistiness, and notoriety of Great White Sharks as predators bring the thrill to cage divers. ),[125] harbour porpoises (Phocoena phocoena),[69] and Dall's porpoises (Phocoenoides dalli). [64] Another great white specimen of similar size has been verified by the Canadian Shark Research Center: A female caught by David McKendrick of Alberton, Prince Edward Island, in August 1988 in the Gulf of St.Lawrence off Prince Edward Island. [28] Linnaeus recognized both names as previous classifications. Stomach contained an entire seal. [201] Many states had prohibited the killing or possession of great white sharks prior to national legislation coming into effect. gran canaria or lanzarote in march Hockey (1982) showed that the Canary Islands oystercatcher was a full species distinct from the African oystercatcher . [196] A February 2010 study by Barbara Block of Stanford University estimated the world population of great white sharks to be lower than 3,500 individuals, making the species more vulnerable to extinction than the tiger, whose population is in the same range. [193] Their position is that further research needs to be done before banning practices such as chumming, which may alter natural behaviour. The entire stretch is ideal for taking a breather from the . The great white shark was one of the species originally described by Carl Linnaeus in his 1758 10th edition of Systema Naturae, in which it was identified as an amphibian and assigned the scientific name Squalus carcharias, Squalus being the genus that he placed all sharks in. McCosker and Timothy C. Tricas, an author and professor at the University of Hawaii, suggest that a standard pattern for great whites is to make an initial devastating attack and then wait for the prey to weaken before consuming the wounded animal. [198][199], Fishermen target many sharks for their jaws, teeth, and fins, and as game fish in general. [69] In a similar fashion, I.K. Fergusson also used shark size estimation methods proposed by J.E. Randall to suggest that the MALTA specimen was 5.35.7m (1719ft) long. The angel shark feeds on flatfish, and occasionaly on crustaceans . [52] Unlike adults, juvenile white sharks in the area feed on smaller fish species until they are large enough to prey on marine mammals such as seals. [37] The progression of C. hubbelli characterized shifting diets and niches; by 6.5 million years ago, the serrations were developed enough for C. hubbelli to handle marine mammals. The great white shark (Carcharodon carcharias), also known as the white shark, white pointer, or simply great white, is a species of large mackerel shark which can be found in the coastal surface waters of all the major oceans. [64], While these measurements have not been confirmed, some great white sharks caught in modern times have been estimated to be more than 7m (23ft) long,[69] but these claims have received some criticism. Last month, a 6-year-old child was bitten by a shark while vacationing on Lanzarote, one of the Canary Islands off the coast of West Africa administered by Spain. Another white shark that was tagged off the South African coast swam to the southern coast of Australia and back within the year. The International Union for Conservation of Nature lists the great white shark as a vulnerable species,[1] and it is included in Appendix II of CITES. [153], Of all shark species, the great white shark is responsible for by far the largest number of recorded shark bite incidents on humans, with 272 documented unprovoked bite incidents on humans as of 2012.[19]. Report inappropriate content shropshirenick Shrewsbury, United. [15] It is also protected by several national governments, such as Australia (as of 2018). The white shark is born at approximately 4 feet long and can grow up to about 20 feet long, weighing over 4,000 pounds. The reasons for their migration and what they do at their destination is still unknown. Accordingly, in most recorded shark bite incidents, great whites broke off contact after the first bite. [174] The idea of containing a live great white at SeaWorld Orlando was used in the 1983 film Jaws 3-D. Monterey Bay Aquarium first attempted to display a great white in 1984, but the shark died after 11 days because it did not eat. [8] According to the same study, male great white sharks take 26 years to reach sexual maturity, while the females take 33 years to be ready to produce offspring. Broken down, it is a portmanteau of two Ancient Greek words. Also spotted by charter captain Paul Sundberg and confirmed visually as a great white. [146] The orca held the shark upside down to induce tonic immobility and kept the shark still for fifteen minutes, causing it to suffocate. Ramon Carretero/Getty Images Great white sharks are at around 1.2m (3.9ft) when born, and grow about 25cm (9.8in) each year. Harbor seals (Phoca vitulina) are taken from the surface and dragged down until they stop struggling. [111] Great whites have also been known to eat objects that they are unable to digest. [1] It is included in Appendix II of CITES,[15] meaning that international trade in the species (including parts and derivatives) requires a permit. The sharks attacked all three baits but rejected the sheep carcass. It has been suggested that government licensing strategies may help enforce these responsible tourism. [33][34] Similarities between the teeth of great white and mega-toothed sharks, such as large triangular shapes, serrated blades, and the presence of dental bands, led the primary evidence of a close evolutionary relationship. [128] When hunting sea turtles, they appear to simply bite through the carapace around a flipper, immobilizing the turtle. [11], The great white shark is an apex predator, as it has no known natural predators other than, on very rare occasions, the orca. Their success rate is 55% in the first two hours, falling to 40% in late morning after which hunting stops. [176] Not until September 2004 was the aquarium able to place a great white on long-term exhibit. [63], According to J.E. Randall, the largest white shark reliably measured was a 5.94m (19.5ft) individual reported from Ledge Point, Western Australia in 1987.

[115], Whale carcasses comprise an important part of the diet of white sharks. Great white shark swims up to fishermen Scientists attribute the more than 30-degree spike in temperature to the shark entering another animal's digestive system, and the unexpected plunge. Weight considered far too low for shark of that length, would have been 9,772.37kg if size was accurate, Deep Blue was spotted off of Mexico in 2013, and again off of Hawaii in 2019, John Randall estimated 517cm based on a 28mm tooth; scaling size based on quantity of reported liver oil yielded gives larger estimate, Cowes, Phillip Island, Victoria, Australia. He was exhibited for 55 days, and was released into the wild on the 25th of October the same year. [a] Another name used for the great white around this time was Lamia, first coined by Guillaume Rondelet in his 1554 book Libri de Piscibus Marinis, who also identified it as the fish that swallowed the prophet Jonah in biblical texts. They much prefer seals, which are fat and rich in protein. By HeinPetri. Great white sharks are ovoviviparous, which means eggs develop and hatch in the uterus and continue to develop until birth. Size-based analysis of diet and trophic position of the white shark (, International Union for Conservation of Nature, Monterey Bay Aquarium Great white sharks, Environmental Protection and Biodiversity Conservation (EPBC) Act, 10.2305/IUCN.UK.2019-3.RLTS.T3855A2878674.en, "Largest Great White Shark Don't Outweigh Whales, but They Hold Their Own", "New study finds extreme longevity in white sharks", "Great white shark amazes scientists with 4,000-foot dive into abyss", "ISAF Statistics on Attacking Species of Shark", "Here's Why We've Never Been Able to Tame the Great White Shark", "Great White Shark Attacks: Defanging the Myths", "2020 was an 'unusually deadly year' for shark attacks, with the most deaths since 2013", "Family Lamnidae - Mackerel sharks or white shark", "Sharks Were Once Called Sea Dogs, And Other Little-Known Facts", "Body dimensions of the extinct giant shark, 10.1671/0272-4634(2006)26[806:ttaotg]2.0.co;2, "The Early Pliocene extinction of the mega-toothed shark, "The occurrence of early Pleistocene marine fish remains from the Gulf Coast of Mobile County, Alabama", "Quantifying habitat selection and variability in habitat suitability for juvenile white sharks", "North Pacific warming shifts the juvenile range of a marine apex predator", "South Africa Australia South Africa". ] a great white sound really stupid are there sharks in its `` shark control '' program government strategies.
