While these measurements have not been confirmed, some great white sharks caught in modern times have been estimated to be more than 7 m (23 ft) long, but these claims have received some criticism. However, J. E. Randall believed that great white shark may have exceeded 6.1 m (20 ft) in length. A great white shark was captured near in on 1 April 1987. This shark was estimated to be more than 6.9 m (23 ft) long by Peter Resiley, and has been designated as KANGA. Another great white shark was caught in by Alfredo Cutajar on 16 April 1987. This shark was also estimated to be around 7.13 m (23.4 ft) long by John Abela and has been designated as MALTA. However, Cappo drew criticism because he used shark size estimation methods proposed by J. E. Randall to suggest that the KANGA specimen was 5.8–6.4 m (19–21 ft) long. In a similar fashion, I. K. Fergusson also used shark size estimation methods proposed by J. E. Randall to suggest that the MALTA specimen was 5.3–5.7 m (17–19 ft) long. However, photographic evidence suggested that these specimens were larger than the size estimations yielded through Randall's methods. Thus, a team of scientists—H. F. Mollet, G. M. Cailliet, A. P. Klimley, D. A. Ebert, A. D. Testi, and —reviewed the cases of the KANGA and MALTA specimens in 1996 to resolve the dispute by conducting a comprehensive analysis of the remains of these sharks and re-examination of photographic evidence in an attempt to validate the original size estimations and their findings were consistent with them. The findings indicated that estimations by P. Resiley and J. Abela are reasonable and could not be ruled out. A particularly large female great white nicknamed "Deep Blue", estimated measuring at 6.1 m (20 ft) was filmed off Guadalupe during shooting for the 2014 episode of "Jaws Strikes Back". Deep Blue would also later gain significant attention when she was filmed interacting with researcher Mauricio Hoyas Pallida in a viral video that Mauricio posted on on 11 June 2015. Deep Blue was later seen off Oahu in January 2019 while scavenging a sperm whale carcass, whereupon she was filmed swimming beside divers including dive tourism operator and model in open water. A particularly infamous great white shark, supposedly of record proportions, once patrolled the area that comprises , South Africa, was said to be well over 7 m (23 ft) during the early 1980s. This shark, known locally as the "Submarine", had a legendary reputation that was supposedly well-founded. Though rumours have stated this shark was exaggerated in size or non-existent altogether, witness accounts by the then young Craig Anthony Ferreira, a notable shark expert in South Africa, and his father indicate an unusually large animal of considerable size and power (though it remains uncertain just how massive the shark was as it escaped capture each time it was hooked). Ferreira describes the four encounters with the giant shark he participated in with great detail in his book Great White Sharks On Their Best Behavior., Shark in Guadalupe Island Biosphere Reserve, Mexico. Great white sharks live in almost all coastal and offshore waters which have water temperature between 12 and 24 °C (54 and 75 °F), with greater concentrations in the United States (Northeast and California), South Africa, Japan, Oceania, Chile, and the Mediterranean including the Sea of Marmara and Bosphorus., The blue shark (Prionace glauca), also known as the great blue shark, is a species of requiem shark, in the family Carcharhinidae, which inhabits deep waters in the world's temperate and tropical oceans. Averaging around 3.1 m (10 ft) and preferring cooler waters, the blue shark migrates long distances, such as from New England to South America..
A quarter of the world’s sharks and rays are threatened with extinction according to The IUCN Red List of Threatened Species™, with ray species found to be at a higher risk than sharks. The findings are part of the first ever global analysis of these species carried out by the IUCN Shark Specialist Group (SSG)., Most sharks feed on smaller fish and invertebrates, while some larger species prey on marine mammals. 7 Shark Species That Aren't Dangerous. By Sunil Purushe , 2. Megamouth sharks are the only living species in their genus. They are unlike any other shark today, and the only living species in the genus Megachasma, which has two extinct megamouth species. 3. The megamouth shark is not luminous. The megamouth shark is believed to be luminous although no histological study has been performed to confirm this., This variety of shark can grow approximately 6.4 m (21 ft) in length in males (although some have reported about great white sharks measuring over 8 m (26 ft)and over 3,324 kg (7,328 lbs) in weight. This shark becomes mature at around 15 years of age and was believed to have a life span of about 30 years or more than that., Bull sharks rarely eat Archosargus probatocephalus, members of the family Carangidae, Cynoscion, and even members of their own species. There is a general pattern of the shark’s diet as they mature. In the younger stages, they feed on fish that are ray-finned. Then as they age they start to consume other elasmobranchs., .
