About this ranking

How it is measured: The number of fish species classified as threatened. Our World in Data chart "fish-species-threatened" (column en_fsh_thrd_no); most recent year per country within the last five years of data, regional aggregates excluded. Caveat: Years differ by country; the chart page documents the original source and its limitations. Data from Our World in Data (CC BY 4.0) and the sources it cites. The full top 50 is on this page, with positions 11 to 50 one click away, and each entry links to its own profile showing every ranking it appears in.
Use this page to check who is number one right now, compare any two entries head to head, or test yourself with the quiz, which asks you to name all ten in three minutes. Year-end archives are available for 2026, freezing the ranking as it stood at the close of each year. Top10Earth never estimates or edits a value: each number is fetched from its source, hashed, stored and ranked by software, then checked by a quality gate before it is published. If a refresh fails the gate, the previous snapshot stays live and the problem is reviewed by a person.
