The toxicity of the fresh water puffer Tetrodon leiurus was analysed. All the organs examined found to be toxic. Among then, the ovary was the strongest in toxicity, followed by the skin. Other organs were less toxic than the ovary and the skin, but contained considerable amounts of toxin. The liver, one of the most toxic organs in the Japanese species in general, was the weakest in toxicity. The distribution of hthe toxin in this species was similar to that of puffers in the South Seas. The toxin isolated from the ovary was identified as tetrodotoxin. Minor toxic components could not be found.
