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 basking shark (Cetorhinus maximus) is the second-largest living shark and fish, [4] after the whale shark. It is one of three plankton-eating shark species, along with the whale shark and megamouth shark. Typically, basking sharks reach 7.9 m (26 ft) in length.
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 100 species with longest life-spans recorded and verified [1] This is a list of the longest-living biological organisms: the individual(s) (or in some instances, clones) of a species with the longest natural maximum life spans. For a given species, such a designation may include:
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 ...
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.

"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 average length of maturity for sharks averages in the greater equatorial and southwestern Atlantic is 170 cm (67 in) for females and 170–190 cm (67–75 in) for males. [19] In the Pacific, sharks appear to mature at four to five years. [17] One oceanic whitetip shark was estimated to have lived 22 years. [5] [20]
