The six gill shark can actually grow up to 8 metres in length as provided by David Attenborough on the blue planet series 1 episode 2 "the deep" Lethbridge101 (talk) 00:59, 4 May 2016 (UTC)

Scientific sources for maximum total length (TL) of Hexanchus griseus
I can find only a single source cited for a maximum TL of 8 meters for the sixgill shark (Hexanchus griseus). I have found, via Google Scholar, at least two articles in the scientific literature which state a maximum TL of 482 cm. The second article does mention reports of a maximum TL of 800 cm in the literature, but that this measurement was “considered erroneous,” though TL of 500 cm ”would not be unexpected,” according to the conclusions of the article’s authors. I could not find a reputable shark science website that mentions a maximum TL of 8 meters. This indicates an inconsistency between the BBC documentary claim and more up-to-date scientific literature. I would think the latter more reliable than the former. Should the BBC source and claimed be replaced by these other sources? Darkprose (talk) 18:28, 30 July 2018 (UTC)
 * The claim comes from Francis Day's Fishes of Great Britain and Ireland (1880-1884), which states the longest specimen, caught off Portugal in 1846, was 26.5 feet long. The original source though says it was only 2.3 feet long. It was simply a typo. I corrected the article and added a citation. BulbousCow (talk) 00:33, 11 April 2022 (UTC)
