The great white shark, 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. It is the only known surviving species of its genus Carcharodon. The great white shark is notable for its size, with the largest preserved female specimen measuring 5.83 m (19.1 ft) in length and around 2,000 kg (4,410 lb) in weight at maturity. However, most are smaller; males measure 3.4 to 4.0 m, and females measure 4.6 to 4.9 m on average. 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, making it one of the longest lived cartilaginous fishes currently known. 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. Great white sharks can swim at speeds of 25 km/h (16 mph) for short bursts and to depths of 1,200 m (3,900 ft).
Requiem sharks are sharks of the family Carcharhinidae in the order Carcharhiniformes. They are migratory, live-bearing sharks of warm seas and include such species as the bull shark, lemon shark, spinner shark, blacknose shark, blacktip shark, grey reef shark, blacktip reef shark, silky shark, dusky shark, blue shark, copper shark, oceanic whitetip shark, and whitetip reef shark.
The oceanic whitetip shark is a large pelagic requiem shark inhabiting tropical and warm temperate seas. It has a stocky body with long, white-tipped, rounded fins. The species is typically solitary, though they may gather in large numbers at food concentrations. Bony fish and cephalopods are the main components of its diet and females give live birth.
The grey reef shark or gray reef shark is a species of requiem shark, in the family Carcharhinidae. One of the most common reef sharks in the Indo-Pacific, it is found as far east as Easter Island and as far west as South Africa. This species is most often seen in shallow water near the drop-offs of coral reefs. It has the typical "reef shark" shape, with a broad, round snout and large eyes. It can be distinguished from similar species by the plain or white-tipped first dorsal fin, the dark tips on the other fins, the broad, black rear margin on the tail fin, and the lack of a ridge between the dorsal fins. Most individuals are less than 1.88 m (6.2 ft) long.
The silky shark, also known by numerous names such as blackspot shark, gray whaler shark, olive shark, ridgeback shark, sickle shark, sickle-shaped shark and sickle silk shark, is a species of requiem shark, in the family Carcharhinidae, named for the smooth texture of its skin. It is one of the most abundant sharks in the pelagic zone, and can be found around the world in tropical waters. Highly mobile and migratory, this shark is most often found over the edge of the continental shelf down to 50 m (164 ft). The silky shark has a slender, streamlined body and typically grows to a length of 2.5 m. It can be distinguished from other large requiem sharks by its relatively small first dorsal fin with a curving rear margin, its tiny second dorsal fin with a long free rear tip, and its long, sickle-shaped pectoral fins. It is a deep, metallic bronze-gray above and white below.
Shark cage diving is underwater diving or snorkeling where the observer remains inside a protective cage designed to prevent sharks from making contact with the divers. Shark cage diving is used for scientific observation, underwater cinematography, and as a tourist activity. Sharks may be attracted to the vicinity of the cage by the use of bait, in a procedure known as chumming, which has attracted some controversy as it is claimed to potentially alter the natural behaviour of sharks in the vicinity of swimmers.
Fabien Cousteau is an aquanaut, ocean conservationist, and documentary filmmaker. He has a 12 year old daughter. As the first grandson of Jacques Cousteau, Fabien spent his early years aboard his grandfather's ships Calypso and Alcyone, and learned how to scuba dive on his fourth birthday. From 2000 to 2002, he was Explorer-at-Large for National Geographic and collaborated on a television special aimed at changing public attitudes about sharks called "Attack of the Mystery Shark". From 2003 to 2006, he produced the documentary "Mind of a Demon" that aired on CBS. With the help of a large crew, he created a 14-foot, 1,200-pound, lifelike shark submarine called "Troy" that enabled him to immerse himself inside the shark world.
Rodney Winston Fox is an Australian film maker, conservationist, survivor of an attack by a great white shark, and one of the world's foremost authorities on that species. He was inducted into the International Scuba Diving Hall of Fame in 2007. He was born in Adelaide.
The 1992 cageless shark-diving expedition was the world's first recorded intentionally cageless dive with great white sharks, contributing to a change in public opinions about the supposed ferocity of these animals.
Ron Josiah Taylor, AM was a prominent Australian shark expert, as is his widow, Valerie Taylor. They were credited with being pioneers in several areas, including being the first people to film great white sharks without the protection of a cage. Their expertise has been called upon for films such as Jaws, Orca and Sky Pirates.
The silvertip shark is a large species of requiem shark, in the family Carcharhinidae, with a fragmented distribution throughout the tropical Indian and Pacific Oceans. It is often encountered around offshore islands and coral reefs, and has been known to dive to a depth of 800 m (2,600 ft). The silvertip shark resembles a larger and bulkier grey reef shark, but can be easily identified by the prominent white margins on its fins. It attains a maximum length of 3 m (10 ft).
Shark tourism is a form of eco-tourism that allows people to dive with sharks in their natural environment. This benefits local shark populations by educating tourists and through funds raised by the shark tourism industry. Communities that previously relied on shark finning to make their livelihoods are able to make a larger profit from diving tours while protecting the local environment. People can get close to the sharks by free- or scuba diving or by entering the water in a protective cage for more aggressive species. Many of these dives are done by private companies and are often baited to ensure shark sightings, a practice which is highly controversial and under review in many areas.
Peter R. Gimbel was an American filmmaker and underwater photojournalist.
The Reef is a 2010 Australian survival horror film, written, directed and produced by Andrew Traucki in his second feature film. The film is about a group of friends who capsize while sailing to Indonesia and are stalked by a great white shark as they try to swim to a nearby island.
A bait ball, or baitball, occurs when small fish swarm in a tightly packed spherical formation about a common centre. It is a last-ditch defensive measure adopted by small schooling fish when they are threatened by predators. Small schooling fish are eaten by many types of predators, and for this reason they are called bait fish or forage fish.
Shark: Mind of a Demon With Fabien Cousteau was a 2006 documentary/reality television special. The film was the result of an attempt by Fabien Cousteau to study the great white shark in its natural surroundings using a submarine shaped like a shark called Troy.
Dangerous Reef is an island and reef system located in the Spencer Gulf in the Australian state of South Australia about 32.5 kilometres (20.2 mi) east-southeast of the city, Port Lincoln. It is the southernmost member of the Sir Joseph Banks Group. It has been the site of a navigation aid since 1911. It is notable as the site of a breeding colony of Australian sea lions. The waters adjoining its shore are notable as a place to view great white sharks to the extent that it was both a popular gamefishing and shark cage diving venue during the twentieth century, and was used to film footage for the following motion pictures – Blue Water White Death and Jaws. The island has enjoyed protected area status since 1900 and it has been part of the Sir Joseph Banks Group Conservation Park since 1989.
Valerie May Taylor AM is an Australian conservationist, photographer, and filmmaker, and an inaugural member of the diving hall of fame. With her husband Ron Taylor, she made documentaries about sharks, and filmed sequences for films including Jaws (1975).
Open Water 3: Cage Dive is a 2017 Australian found footage survival horror film directed and written by Gerald Rascionato and released by Lionsgate as part of the Open Water film series, although the film is a stand-alone sequel and only connects to the other films in theme, not continuity. It follows a trio of Americans on vacation in Australia who are also filming an audition tape for an extreme reality TV show on a cage diving excursion. Before they know it, a rogue wave capsizes and sinks their boat leaving them stranded in the ocean. The film is presented as a mockumentary and perpetuated as true events; though most of the film is first person footage from the characters with time stamps throughout the film, in the vein of Paranormal Activity. The film bears similarities to another 2017 shark attack survival film featuring a cage dive excursion gone wrong, 47 Meters Down. The method of "cage dive disaster" in each film differs with Open Water 3: Cage Dive involving a rogue wave capsizing the boat while the former film sees a rusty winch break, trapping the protagonists underwater within the cage. The notable difference between these two films is that Cage Dive does not keep its protagonists within the cage, but rather leaves them in the open water among hungry sharks.
Deep Blue is a female great white shark that is estimated to be 6.1 m (20 ft) long or bigger and is now sixty years old. She is believed to be one of the biggest ever recorded in history. The shark was first spotted in Mexico by researcher Mauricio Hoyos Padilla. Deep Blue was featured on the Discovery Channel's Shark Week. The shark was spotted by marine biologists studying tiger sharks near the island of Oahu, Hawaii. Various videos show the shark as calm and non-aggressive around humans and even dolphins.
