Takifugu
genus of fishes
Takifugu, also known by the Japanese name fugu (河豚; lit. "river pig"), is a genus of pufferfish currently with 25 species. Most are native to salt and brackish waters of the northwest Pacific, but a few species are found in freshwater in Asia or more widely in the Indo-Pacific region. Their diet consists mostly of algae, molluscs, invertebrates and sometimes crustaceans.
These fish contain lethal amounts of tetrodotoxin in the internal organs, especially the liver and the ovaries, but also in the skin and the testes. The toxin paralyzes the muscles while the victim stays fully conscious, and eventually dies from asphyxiation. There is currently no antidote, and the standard medical approach is to try to support the respiratory and circulatory system until the effect of the toxin wears off.
Distribution and conservation status
Currently, 25 species are placed in the genus Takifugu. Most species are restricted to salt and brackish waters of the northwest Pacific, but a few occur more widely in the Indo-Pacific region or in freshwater of Asia. Although several are euryhaline to some extent, most are unable to live in freshwater.
Begin with the source’s own compact description: “Takifugu” is genus of fishes. The dossier treats that line as a proposition to test through Takifugu, genus and fishes, not as a finished interpretation.
Why this record matters
The phrase “genus of fishes” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 28, 2026. The linked authority identifier is Q387587. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
