Pufferfish in 1960s: TTX structure
[92] [pufferfish-3-92] In 1960s, the field log for Pufferfish is headed “TTX structure.” The figure kept beside that heading is 2002. It is a count or a date from the work, not a rank of the species’ worth. A zoo birthday card does not replace the log. Field guides collapse many lineages into the word pufferfish. Subspecies, flyways and captive lines do not share one fate.
Beak-toothed inflators whose tetrodotoxin made a Japanese cuisine and a genome project out of one family. No. Toxin load varies by species, organ and season. Licensed fugu service still treats liver as forbidden in many prefectures after historic poisonings. Why was Takifugu rubripes sequenced so early?
A compact genome (about 400 Mb) made it a 2002 model in Nature -- a puffer as a human-genome shortcut, not a menu story. 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.
Keep 1960s, “TTX structure,” and 2002 together or the note on Pufferfish stops being that year’s record.1960s
