Where the facts come from

Every factual claim on this site links to its source. This is the full list.

How we checked

Each fact was written alongside its source. Our build script stores the source text and, for every fact, checks that the key words and figures really appear in it. 136 of 136 checks passed when this site was last built (October 2026). Where we couldn’t find a source we could read, we left the claim out.

Main sources: the Shark Trust, the International Shark Attack File, Manx Wildlife Trust, Manx Whale and Dolphin Watch, the journal Nature, and Wikipedia (for widely established biology).
