 * Research 75 facts with sources:

1.) L arge [|la][|mniform] [|sha][|rk] found in coastal surface waters in all major [|oceans]. 2.) Reaching lengths of more than 6 metres (20 ft). 3.) Weighing up to 2,240 kilograms (4,938 lb). 4.) The great white shark is arguably the world's largest known predatory [|fish.] 5.) [|Carolus Linnaeus] gave the great white shark its first scientific name. 6.) //Squalus carcharias is it's scientific name. 7.) [|Sir Andrew Smith] gave it the [|generic] name //Carcharodon //in 1833// 8.) In 1873 the generic name was identified with Linnaeus specific name and the current scientific name //Carcharodon carcharias// was finalised. 9.) Carcharodon comes from the [|Greek] words //karcharos,// witch means sharp or jagged. 10.) //O////dous// means tooth. 11.) The great white is classified as a mackerel ([|Lamnidae]) shark 12.) There are four other living species in this [|family], two [|mako] and two //[|Lamna]// sharks. 13.) Dental features and the extreme size of both the great white and the [|prehistoric] [|Megalodon] led many scientists to believe they were closely related, and the name //Carcharodon megalodon// was applied to the latter. 14.)At present there is considerable doubt about this hypothesis, as many scientists would place the megalodon and white shark as distant relatives - sharing the family Lamnidae but no closer relationship. 15.)Latest research suggests that the great white shark is more closely related to the [|mako shark] than to the megalodon. 16.)According to this theory, the extinct broad-tooth mako, //Isurus hastalis//, is considered to be the true ancestor of the great white, while the megalodon has strong ties with the sharks belonging to //Carcharocles// genus.

17. S harks have existed as a group for over 350 million years. 18. Sharks and rays (elasmobranchs) are represented by over 600 species that show a remarkable range of ecological and morphological diversity. 19. Unlike the true fishes, sharks do not have internal bone, but instead have a cartilaginous skeleton. 20. Although many people are told that sharks are primitive in comparison to other groups, this is not true. 21. The white shark is found in temperate waters throughout the world's oceans, and it is an important, though not common, predator in California's coastal habitats. 22. White sharks are predatory animals that begin life by feeding on fish, rays, and other sharks, and as they grow, switch to feeding on marine mammals and scavenging on large animal carcasses. 23. Their first mammalian prey are usually the small harbor seal. 24. As the sharks increase in size, they become large enough to eat sea lions, elephant seals, and small toothed whales. 25. Attack strategy consists of a swift, surprise attack from below, inflicting a large, potentially fatal bite. 26. The pinniped often dies from massive trauma or blood loss, but the bites may be superficial or misplaced on the body, allowing the seal to escape and survive the attacks with their scars as witness. 27. Large white sharks will also scavenge on the carcasses of whale sharks, and on the fat-rich blubber layer of dead whales. 28. They will occasionally feed on sea turtles and sea otters, and are known to attack, but not eat, humans. 29. The waters off central California offer a rich bounty of food for white sharks, and every summer and fall they actively feed in nearshore areas. 30. Farallon Islands, a national wildlife refuge about 27 miles off San Francisco, is a common feeding ground for the sharks. 31. Four species of pinnipeds, the northern elephant seal, the California sea lion, the Steller sea lion, and the harbor seal, live around and breed on these islands, making a plentiful food resource for the white sharks. 32. The coastal waters along central California, especially around the Año Nuevo State Reserve and along the Marin Headlands, is another common feeding area for the sharks 33. In the summer the sharks feed on seals and sea lions along the coast as far north as Oregon and occasionally the Gulf of Alaska, and in the Fall, they turn south and feed along the offshore islands. 33. It is believed that female white sharks migrate to southern California to give live birth to their offspring. 34. In abnormally warm-water (El Niño) years, white sharks are more plentiful off central California because both they, and their prey, are shifted north. 35. The years 1984-84 and 1991-92 show high trends in white shark predatory activity, and were the warmest oceanic seasons in recent history.

[] 36. Great White Sharks are the largest predatory fish in the sea.

37. Great White Shark meat is not recommended for human consumption because it has very high mercury levels.

38. Great White Sharks try to avoid fighting for food. When there is only enough food for one, they have a tail-slapping contest. The sharks swim past each other, each slapping the surface of the water with their tails, and often directing the spray toward the other shark. The one who gets the meal is the shark that delivers the most tail slaps.

39. Great White sharks live along the coasts of all continents except Antarctica.

40. The Great White Shark have an enormous liver that can weigh up to 24 percent of its entire weight.

41. A Great White Shark may use and lose more than one thousand teeth in its life time.

42. The Great White Shark is not all white. The shark’s back may be dark blue, gray, brown or black.

43. The Great White Shark lives for about 25 years.

44. A Great White Shark is capable of eating sea lions whole.

45. Great White Sharks rarely attack people and when they do, it is because they mistaken the person for their usual seal prey.

46. Great Whites often have scratches and scars on their snouts which resulted from their prey fighting back.

47. Scientists estimate that after a big meal, a Great White Shark can last up to three months before needing another one.

48.A Great White Shark can roll its eyeballs back, which protects the vital front part of the eye from being scratched.

49. Young Great White Sharks eat Leopard Sharks.

50. A Great White Shark was once kept in an aquarium for a few days, but it became disoriented, continually hitting its nose against the glass, so it had to be released into the sea.

51. The biggest Great White Shark ever caught was off Prince Edward Island in 1993. It was 20 feet long. In one year, a single Great White consumes about 11 tons of food.

52. Some scientists believe there are less than 10,000 Great White Sharks in the entire world. **

53. Great White Sharks breed late in life. They do not start breeding until they’re at least twenty years old. More than 70 percent of known victims of Great White Shark Attacks survive because the shark realizes it has made a mistake and doesn’t finish off the prey.

54. Great White Sharks are no match for Orcas in a fight. Orcas, better known as Killer Whales, sometimes hunt in packs plus they are too fast and strong for even the biggest Great Whites. Orcas have been known to kill and eat them as well.

[] 55. Sharks can feel 1 part blood of an animal in 100 million parts of water 56. On average, sharks have killed less people than __[|vending machines]__ 57. 90% of sharks have been killed by man 59. The dwarf shark is smaller than your hand 61. One big meal can keep a shark going for 3 months because it uses so little __[|energy] __swimming 62. Sharks have been around for over 300 million years, even before dinosaurs 63. More people are killed by bee stings than sharks 64. Sharks attack more men then women; no one knows why 65.The longest shark teeth ever found are 6 inches long. They belonged to a Carcharodon Magaloden shark. This shark is extinct and lived 4.5 million years ago. 66. The swell shark, found in New Zealand barks like a dog 67. A shark can go through up to 1,000 sets of teeth during its life

[] 69. Unlike most bony fish, shark's eggs are fertilized inside the female's body. The male shark has "claspers," extensions of the pelvic fins that are used to transfer sperm to the female and fertilize her eggs.

70. Most sharks give birth to live young, but some release eggs that hatch later. The gestation period (the time the embryo spends inside the female, developing) can be up to almost two years long (the spiny dogfish shark may have the longest shark gestation period).

71. Baby sharks (called pups) are born with a full set of teeth and are fully ready to take care of themselves. They quickly swim away, even from their mothers who might eat them. Litter size ranges from one or two pups (for a great white shark) to over 100 (for a large blue shark and the whale shark).

[|http://www.swordfishingcentral.com/great-white-0. ark-facts.html] 73. Before movies such as Jaws and Shark Attack Movie, Great White Sharks did not have much of a reputation in the public eye. The number of shark attacks on humans has not been significant enough to warrant a real scare from beach goers and boaters.

74. Great white sharks serve a significant purpose in today’s ecology. You can be sure that they feed on meat such as seals, sea lions, and turtles. They even feed on injured, sick, and diseased, thus cleaning up the ocean and future spreading of plague.

75. Scientists have studied great white sharks for many years and each year discovers more interesting facts about the life of the white shark.

76. While great white sharks have become a protected species, man is still the species biggest threat. Whether the fish are killed while netting bait fish or accident caught via long line fishing for swordfish and other commercial species, the great white shark continually is at risk.

77. While a white shark has poor vision, it become susceptible to such risk and causes death many time each year.

[] Description
 * 78. Encryption:** Profile is much like the Mako’s, except proportionately trimmer. Color varies from overall grayish white to brownish above and white below. Usually looks lighter in the water than other big sharks. Nose is pointed; teeth triangular and serrated. A black patch may be present at base of pectoral fin.
 * SIZE:** Might be 200 or 2,000 pounds. The largest of all predatory Sharks, it has been verified at 20 feet and over 4,000 pounds. World record 2,664 pounds; Florida record 686 pounds.
 * FOOD VALUE:** From whose viewpoint: the angler’s or the Shark’s? White Shark steaks are probably fair to good, but who really knows?
 * GAME QUALITIES:** Size and rarity alone place it among the ultimate angling challenges. The Great White, as a matter of fact, ranks as the largest species of fish ever caught by sportfishing methods.
 * TACKLE AND BAITS:** For big specimens, the heaviest sporting tackle available is never too heavy. Best baits are large dead fish, such as Tuna, Dolphin or Bonito—or the same bait fished live, when available. Florida, catches are opportunistic, usually coming as a surprise to anglers who are seeking more common species of Sharks.
 * FISHING SYSTEMS:** Drift Fishing; Still Fishing.
 * RANGE:** Occurs, if rarely, off all Florida coasts, the Bahamas and the Caribbean. Prefers cooler water than ours, and no more than a couple are reported in Florida during a typical angling year. More often than not, the occasional catch of a Great White is made in the Florida Keys.
 * HABITAT:** The open sea.

A large, stout, spindle-shaped shark with a pointed snout. Blue or brownish above, turning abruptly white on lower side and onto belly; dusky spot behind pectoral fin. Teeth serrate; upper teeth broadly triangular. Gill openings rather large but not extending onto back or belly. Second dorsal and anal fins small. Origin of anal fin well behind second dorsal. Origin of first dorsal over free rear tip of pectoral fin. Caudal fin lunate, with upper and lower lobes nearly equal in size. Large lateral keel on each side of caudal peduncle but no secondary keels on caudal fin base. Total length (TL) commonly to 17'5" (5.3 m); maximum recorded TL 21' (6.4 m). Similar Species Mako sharks (genus Isurus) are similar but have smooth-edged teeth and more slender bodies, with first dorsal origin well behind pectoral fin base, and lack spot behind pectoral fin. Habitat Coastal waters, usually near surface. May make long migrations across open seas. Range Temperate waters of all oceans. On Atlantic Coast south from s. Newfoundland to Brazil (reported to Argentina), as well as Gulf of Mexico, Bahamas, Cuba, and Lesser Antilles. On Pacific Coast from Alaska south to Gulf of California. Discussion The Great White Shark (officially called just the White Shark) feeds on a variety of fish, including other sharks, as well as sea lions, birds, sea otters, sea turtles, carrion, and, occasionally, undigestible garbage. Little is known about its reproduction, although it probably retains the eggs in the uterus until they hatch; intrauterine cannibalism is likely. The young are about 5' (1.5 m) long at birth. Females are rarely seen. The White Shark can grow quite massive--a 21-foot (6.4 m) specimen taken off Cuba weighed 7,100 pounds (3,220 kg)--but reports of a 36-foot (11 m) White Shark are certainly erroneous. This fish is occasionally caught by commercial fishermen, and the flesh is reportedly quite palatable.

 * = =Growth=
 * = Pups are 4-5 feet long at birth and weigh about 40 pounds. ||
 * = A typical adult great white shark measures 4–4.8 [|metres] (13–16 [|ft]) and has a mass of 680–1,100 [|kilograms] (1,500–2,400 [|lb])..,l ||

 * = Enables them to detect the electromagnetic field emitted by the movement of living animals. ||
 * = To more successfully hunt fast moving and agile prey such as sea lions, the great white shark has developed adaptations that allow it to maintain a body temperature warmer than the surrounding water. ||
 * = One of these adaptations is a "[|rete mirabile]" (Latin for "wonderful net"). ||
 * = This close web-like structure of veins and arteries, located along each lateral side of the shark, conserves heat by warming the cooler arterial blood with the venous blood that has been warmed by the working muscles. ||
 * = This keeps certain parts of the body (particularly the brain) at temperatures up to 14 °C (25 °F)[|[15]] above the surrounding water, while the heart and gills remain at sea-temperature. ||
 * = When conserving energy (a great white shark can go weeks between meals), the core body temperature can drop to match the surroundings. ||
 * = A great white shark's success in raising its [|core temperature] is an example of [|gigantothermy]. ||

= Hello this is Flobble with Bob the shark, How are you today Bob. Well I'm kind of felling hungry. O.K. let's get down to business. = =Interview with Mr. SharkFlobble: Do you have a swim blatter? Shark: No, I don't.Flobble: Are you related to any thing? Shark: Not really, but I look a little bit like the mako, And I'm sort of related to the Meglodon.=

=Flobble: What do you eat? Shark: I eat seal, whale carcasses, and other sharks.Flobble: How do you eat? Shark: I role my eyelid back and go all the way down to 1,000 ft. then swim all the way down, and snatch.=

=Flobble: What are the names of your babies? Shark: They are called pups.Flobble: How old are you when you mate? Shark: 15 years of age.Flobble: What is your ribcage made of? Shark: It is made of cartilage.Flobble: How do they work? Shark: They work like human bones.Flobble: How long can pups grow? Shark: 4-5 feet.Flobble: What are your teeth like? Shark: They are serrated. Flobble: What are your gill openings like? Shark: Well they are r... ath..er I need water!!O.K. lets try that again. Shark:Well they are rather large, but they aren't extended onto the back.Flobble: How can you sense your prey? Shark: I have a magnetic field.=

**Sharks have been around for 400 million years!! They were around for longer than the dinosaurs. They were about 65ft.long! They use to eat whales! They were like the kings of the sea. Now they aren’t as big, but they are still almost as deadly. They eat seals. They also still eat whale, but when there dead only. They live at the top of the Twilight zone. When they mate, they are aggressive. They bight mate!** Friendly Letter   Dear Mr. Colossal Squid,  Would you stop coming up to the twilight zone. I would like it if you stop, so I can go hunt with out you hunting me. I would also like it if you would stop hunting my pups. I would also like to enjoy my whale Caracas. If you don't I will get a hole bunch of other sharks to kill you.

Sincerely, Mrs. Shark
