Greenland sharks are recognized as the longest-lived vertebrates on earth. They have a slow growth rate, late maturity period, and low fecundity, making the management and conservation of this species very important. As a result of their low productivity and extreme longevity, this species is particularly susceptible to overfishing and bycatch ...
The Greenland shark had been estimated to live to about 200 years, but a study published in 2016 found that a 5.02 m (16.5 ft) specimen was between 272 and 512 years old. [75] [76] That makes the Greenland shark the longest-lived vertebrate. [77] The maximum lifespan of the freshwater pearl mussel (Margaritifera margaritifera) may be 210–250 ...
Whale sharks (Rhincodon typus) may also live over 100 years. [69] Earlier estimates suggested the Greenland shark (Somniosus microcephalus) could reach about 200 years, but a recent study found that a 5.02-metre-long (16.5 ft) specimen was 392 ± 120 years old (i.e., at least 272 years old), making it the longest-lived vertebrate known.

But, in reality one of the ocean's largest sharks lives here. Nicknamed the sleeper shark, Greenland sharks are very slow moving and mostly Mysterious giant sharks may be everywhere
In spite of official protections in Australia, great white sharks continue to be killed in state "shark control" programs within Australia. For example, the government of Queensland has a "shark control" program (shark culling) which kills great white sharks (as well as other marine life) using shark nets and drum lines with baited hooks.
"The new shark is certainly grotesque, [...] the most remarkable feature is the curiously elongated nose." [39] A few specimens have been collected alive and brought to public aquariums, though they only survived briefly. One was kept at Tokai University and lived for a week, while another was kept at Tokyo Sea Life Park and lived for two days.
The largest kind of shark is called the whale shark, which has been known to get as large as 60-feet long, the Smithsonian Institute said. Whale sharks feed on planktonic organisms including krill ...
The thresher shark mainly feeds on schooling pelagic fish such as bluefish, juvenile tuna and mackerel, which they are known to follow into shallow waters, as well as squid and cuttlefish. [16] Crustaceans and occasionally seabirds are also eaten. The thresher shark stuns its prey by using its elongated tail as a whipping weapon.
