Pufferfish in 1948s: Postwar poisonings · 583

The fish gulps water into a specialised stomach diverticulum. Spines (in some species) erect. It is a mechanical jam, not a bluff only. Much evidence points to bacterial and food-chain accumulation. Captive-raised puffers can be far less toxic -- a husbandry fact that complicates folklore.

Japan requires training and exams after 20th-century restaurant deaths. The licence is a public-health instrument, not a gourmet badge. Are aquarium puffers the same as fugu? Hobbyists keep freshwater and brackish tetraodontids (e.g. figure-eight, Mbu). They share the beak and inflate; they are not all Takifugu.

Four fused tooth plates continuously grow and must be worn on hard prey -- a dental bill, not a cartoon. Many coastal species are Least Concern; some endemics and heavily fished Takifugu stocks are not. Resilience here is mid-pack, not a free pass. Pufferfish is one of 24 types in this animals atlas. The pages treat it as a full system -- history, anatomy, operating principles, culture, icons, future pressure and market shape -- not a ranking of a best species.
