We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

Bull shark — The maximum recorded length is stated as 3.5 m (11.5 ft) or occasionally up to 3.8 m, but widely accepted maximum is 3.4 m with unconfirmed reports up to 4.0 m; 3.8 m is not a standard figure in reliable sources.
Bull shark — The bite force claim that it is 'the highest weight-for-weight among investigated cartilaginous fishes' is overstated; some sources describe it as one of the highest, not definitively the highest.
Whale shark — The claim that the whale shark's rhodopsin pigment 'becomes unstable in shallow water, where the shark deactivates it' is not established in scientific canon and appears to be an invented or oversimplified claim.
Whale shark — The statement that the whale shark is 'one of the most ancient shark species still extant today' is misleading because many other extant shark lineages have much older fossil records, and the phrasing implies exceptional antiquity not supported by the fossil r
Great white shark — [contradicted] White sharks reproduce with pups hatching from eggs inside the female before being born live :: The source states exactly the same: 'The species reproduces with pups hatching from eggs inside the female before being born live.' There is no contr
Hammerhead shark — [contradicted] Reproduction frequency varies by species; some reproduce annually, others biennially or less :: The source explicitly states: 'Reproduction occurs only once a year for hammerhead sharks' — meaning ALL species reproduce annually, not that frequen
Hammerhead shark — [contradicted] During mating, the male bites the female, a behavior common among sharks, though it is not a matter of 'agreement.' :: The source explicitly states: 'the male shark biting the female shark violently until she agrees to mate with him' — implying
Tiger shark — [contradicted] The tiger shark is not the largest member of the order Carcharhiniformes; that title belongs to the great hammerhead shark :: The source states: 'It is the largest member of the order, commonly referred to as ground sharks.'
Basking shark — [contradicted] The basking shark is usually greyish-brown with mottled skin :: The source states 'It is usually greyish-brown, with mottled skin' — this matches, so no contradiction. However, the 'lore' also says 'the inside of the mouth is white' which is cor
Megalodon — [contradicted] Earliest remains reported from Late Oligocene, around 28 million years ago :: The source states 'the earliest megalodon remains have been reported from the Late Oligocene, around 28 million years ago (Mya), there is disagreement as to when it ap
Megalodon — [contradicted] Earliest remains reported from Late Oligocene, around 28 million years ago; appearance disputed, with dates ranging to as young as 16 million years ago :: The source says 'the earliest megalodon remains have been reported from the Late Oligocene
Great hammerhead — [contradicted] The tagline states 'critically endangered by overfishing' :: The source states it 'has been assessed as critically endangered by the International Union for Conservation of Nature (IUCN) as of 2019' due to population declines from overfishing, w
Great hammerhead — [contradicted] The stat 'Litter size: 2–49 pups every two years' :: The source states 'bearing litters of up to 2-49 pups every two years' — consistent, no contradiction.
