Great White Shark Facts

Great White Shark Facts - The great white shark, Carcharodon carcharias, also known as great white, white pointer, white shark, or white death, is a large lamniform shark found in coastal surface waters in all major oceans. The great white shark is very well known for its size, with the largest individuals known to have approached or exceeded 6 metres (20 ft) in length and 2,268 kilograms (5,000 lb) in weight. It reaches maturity at around 15 years of age and can have a life span of over 30 years. The great white shark is arguably the world's largest known extant macropredatory fish and is one of the primary predators of marine mammals. It is also known to prey upon a variety of other marine animals including fish, pinnipeds, and seabirds. It is the only known surviving species of its genus, Carcharodon.

The best selling novel Jaws and the subsequent blockbuster film by Steven Spielberg depicted the great white shark as a "ferocious man eater". In reality, humans are not the preferred prey of the great white shark.

The IUCN treats the great white shark as vulnerable, while it is included in Appendix II of CITES.

Great White Shark Facts

Males reach maturity at 3.5–4.0 metres (11–13 ft), and females at 4.5–5.0 metres (15–16 ft). Adults on average are 4–5.2 metres (13–17.1 ft) long and have a mass of 680–1,100 kilograms (1,500–2,400 lb). Females are generally larger than males. It is widely accepted that the great white shark can approach 6.1 m (20 ft) in length and 1,900 kg (4,200 lb) in weight.[3] However, the maximum size is still subject to hot debate because such reports are often rough estimations or speculations performed under questionable circumstances.

For several decades, many ichthyological works, as well as the Guinness Book of World Records, listed two great white sharks as the largest individuals: a 10.9 m (36 ft) great white captured in Southern Australian waters near Port Fairy in the 1870s, and a 11.3 m (37 ft) shark trapped in a herring weir in New Brunswick, Canada in the 1930s. Some researchers question these measurements' reliability, noting they were much larger than any other accurately reported sighting. The New Brunswick shark may have been a misidentified basking shark, as the two have similar body shapes. The question of the Port Fairy shark was settled in the 1970s, when J. E. Randall examined the shark's jaws and "found that the Port Fairy shark was of the order of 5 m (17 ft) in length and suggested that a mistake had been made in the original record, in 1870, of the shark's length".

Man Hits Teen on Plane Over iPhone - Police say a man on a Southwest Airlines flight from Las Vegas punched a teenager who refused to turn off his iPhone as the plane approached the Boise airport. Officers arrested 68-year-old Russell E. Miller, of Boise, on suspicion of misdemeanor battery Tuesday. He has been released from jail on bond. Witnesses told police the 15-year-old was playing games and listening to music on his cell phone when flight attendants instructed passengers to turn off their electronic devices because the plane was landing. Witnesses told police that when the teen didn't respond, Miller got angry and punched the boy in the arm. Miller says he "tapped" the teen on the shoulder after he refused to turn off the phone. He told the Idaho Statesman that he may have "overreacted," but that he did not punch the teen. Man Hits Teen on Plane Over iPhone
