Claim: Multiple 65-foot freshwater “Kodiak sharks” have been discovered in Lake Michigan and have attacked swimmers. For example, one TikTok user posted a video on Oct. 4, 2024, claiming multiple 65-feet "Kodiak sharks" were found in Lake Michigan "a few weeks ago." Likewise, the Michigan Department of Natural Resources' public information officer Ed Golder said in an email: "No 'Kodiak shark' has been found in Lake Michigan." Likewise, the Shark Research Institute — a U.S. nonprofit scientific research organization with a focus on shark conservation — makes no mention of a "kodiak shark" on its website. Additionally, parts of the video referencing the "kodiak shark" are animated and not actual footage of the creatures.
