Content:  the 15 individuals tracked, two females were reported as measuring 15 m and 18 m respectively. A 20.75 m long whale shark was reported as being stranded along the Ratnagiri coast in 1995. A female individual with a standard length of 15 m (and an estimated total length at 18.8 m) was reported from the Arabian Sea in 2001. In a 2015 study looking into the size of marine megafauna, McClain and colleagues considered this female as being the most reliable and accurately measured. On 7 February 2012, a large whale shark was found floating 150 km off the coast of Karachi, Pakistan. The length of the specimen was said to be between 11 and 12 m, with a weight of around 15000 kg.

The maximum length of the species is uncertain due to a lack of detailed documentation of the largest reported individuals. Several whale sharks around 18 m (59 ft) in length have been reported. Large whale sharks are difficult to measure accurately, both on the land and in the water. When measured on land, the total length can be affected by how the tail is positioned, either angled as it would be in life or stretched to the maximum possible. Historically, techniques such as comparisons to objects of known size and knotted ropes have been used for in-water measurements and may suffer from inaccuracy. In 2011, laser photogrammetry was proposed to improve in-water measurement accuracy.
Title: Whale shark
Content:  The whale shark is the largest non-cetacean animal in the world. Evidence suggests that whale sharks exhibit sexual dimorphism with regards to size, with males not growing as large as females. A study looked at the growth of whale shark individuals over 10 years. It concluded that males on average reach 8 to 9 meters (26 to 30 ft) in length; although this does not represent the maximum possible size. The same study predicted females reaching a length of around 14.5 m on average, based on more limited data. Previous studies estimating the growth and longevity of whale sharks have produced estimates ranging from 14 to 21.9 m in length. Limited evidence, mostly from males, suggests that sexual maturity occurs around 8 to 9 m

Content:  wa could be interpreted as either 2 m or the approximate average of 1.7 to(-), and weighed approximately 37 tonnes (81,500 lb) based on the local fishermen. Later sources have stated this whale shark as approximately 18 m, with a weight of 43 tonnes, but the accuracy of the estimate has been questioned. In 1934, a ship named the Maunganui came across a whale shark in the southern Pacific Ocean, rammed it, and the shark became stuck on the prow of the ship, supposedly with 15 ft on one side and 40 ft on the other, suggesting a total length of about 55 ft. Scott A. Eckert & Brent S. Stewart reported on satellite tracking of whale sharks from between 1994 and 1996. Out 
Title: Great white shark
Content:  in modern times have been estimated to be more than 7 m long, but these claims have received some criticism. However, J. E. Randall believed that great white shark may have exceeded 6.1 m in length. A great white shark was captured near Kangaroo Island in Australia on 1 April 1987. This shark was estimated to be more than 6.9 m long by Peter Resiley, and has been designated as KANGA. Another great white shark was caught in Malta by Alfredo Cutajar on 16 April 1987. This shark was also estimated to be around 7.13 m long by John Abela and has been designated as MALTA. 
Title: Whale shark
Content:  sharks have estimated whale shark lifespans at 80–130 years. Whale sharks have very large mouths and are filter feeders, which is a feeding mode that occurs in only two other sharks, the megamouth shark and the basking shark. They feed almost exclusively on plankton and small fishes, and pose no threat to humans. The species was distinguished in April 1828 after the harpooning of a 4.6 m specimen in Table Bay, South Africa. Andrew Smith, a military doctor associated with British troops stationed in Cape Town, described it the following year. The name "whale shark" refers to the fish's size, being as large as some species of whales, and also to its being a filter feeder like baleen whales.

In a museum at Beirut, Syria, there is a whale shark head big enough to swallow a man. ; Sperm whales have been reported to swallow squid whole. In 2009, a photograph was taken showing a female sperm whale, with a calf at her side, carrying the remains of a roughly 30-foot (9-meter) giant squid in her jaws, while swimming near the surface off Japan's Bonin Islands (map)in the northwestern Pacific. There is a story of a sailor being swallowed by a sperm whale off the Falkland

Content:  this whale can form an air storage chamber, an enlargement of the nasal sinus, often measuring 7 feet high, 7 feet wide, and 14 feet long. ; In 2011, Mauricio Handler photographed a diver who almost got sucked into the mouth of a massive whale shark during a feeding frenzy where more than 600 of the 40 ft so-called "shark suckers" gathered to feed on tuna spawn. The mouth of a whale shark (Rhincodon typus) can be up to 1.5 m wide, containing up to 350 rows of teeth. This type of shark, the sea's largest fish, is actually incredibly docile, so despite their size, do not pose a risk to divers. The largest

It is also the largest living animal that is not a cetacean and, like the largest whales, it is a docile creature that filter-feeds on tiny plankton. An average adult species measure 9.7 m long and weigh an average of 9 tonnes. The largest verified specimen was caught in 1949 off Karachi, Pakistan and was 12.7 m long and weighed 21.5 tonnes. Although many are dubious, there are several reports of larger whale sharks, with reliable sources citing unverified specimens of up to 37 tonnes and 17 m.             
Title: Deep Blue (great white shark)
Content:  Deep Blue is a female great white shark that is estimated to be 6.1 m (20 ft) long and is said to be over fifty years old. The shark was first spotted in Mexico by Mauricio Hoyos Padilla, a researcher. Deep Blue has been featured on the Discovery Channel's Shark Week. The shark had also been spotted in Hawaii by marine biologists who had been in Oahu to study tiger sharks. Various videos have shown the shark to have been calm and non aggressive around humans and notably even a few dolphins.
