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".

Best Indoor Exercise

Best Indoor Exercise - There are several indoor exercises you can do to keep in shape. But which are the best? They can be split in to two categories.

Kinect Review

Kinect Review - First presented to the world as Project Natal at E3 2009, Microsoft's Kinect sensor peripheral has since been positioned by the software (and hardware) giant as the next phase of Xbox 360's evolution as a platform. A combination of hardware and software, it's been billed as a means for users to interact with their consoles and play games without using a physical controller, using natural gestures, voice commands and face recognition. I've had a final retail Kinect unit at home for a little over a week now, and have had ample time to put the shiny new gadget through its paces. Is it as magical as expected? Will it transform gaming? Or, more importantly, does it even work? Read on past the break for my in-depth review of this ambitious apparatus. Kinect is a single piece of hardware, yet it incorporates several distinct technologies. There's an infrared emitter that floods your play space with invisible light, paired with a CMOS sensor that then l...
