how big is the shark in the movie the shallows
The Shallows (film) While surfing one last time for the day, Nancy notices the carcass of a large humpback whale nearby. As she rides the last wave back to the beach, a large great white shark knocks her off her surfboard and bites her leg. Nancy climbs onto the whale carcass, but the shark rams it from underneath, forcing her to swim to an isolated rock. She uses her surfboard strap to slow the bleeding on her leg. Later she uses her jewelry to put rudimentary stitches in place to hold her torn flesh together. Nancy is left alone when the unaware locals leave the beach, and she spends the night on the rock with a wounded seagull, who was also injured from the whale, she names him Steven Seagull. The next morning, a drunk local man on the beach steals Nancy's belongings. While wading out into the shallow water, to steal Nancy's surfboard, he is killed by the shark. Several hours later, the two locals Nancy had surfed with the day before return. They get into the water before Nancy can warn them away, and are also killed by the shark.
Great white shark The great white shark (Carcharodon carcharias), commonly known as the great white or the white shark, is a species of large mackerel shark which can be found in the coastal surface waters of all the major oceans. The great white shark is notable for its size, with larger female individuals growing to 6.1 m (20 ft) in length and 1,905 kg (4,200 lb) in weight at maturity.[3][4][5] However most are smaller, males measuring 3.4 to 4.0 m (11 to 13 ft) and females 4.6 to 4.9 m (15 to 16 ft) on average.[5][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 fish currently known.[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.[9] Great white sharks can swim at speeds of over 56 km/h (35 mph),[10] and can swim to depths of 1,200 m (3,900 ft).[11]
