| Research Abstract |
We examined to clarify the toxicity, toxin accumulation ability, and the inherited characteristics of hybrid pufferfish, as well as the transfer/accumulation/elimination mechanisms of TTX in the pufferfish body. 20 natural hybrid specimens were collected from coastal waters of Japan, and their parent species were identified by analysis of those mitochondrial and nuclear DNA. Moreover, anatomical distributions of toxicity were clarified by LC/MS analysis. Five hybrids species were contained in 20 specimens, and they were identified as "shimatora", "magoma", "matora", "toragoma" and "torama", respectively. When TTX was administrated to artificial hybrid "torama" and "torakusa", transferred first to the liver and then to the skin and ovary. On the other hand, TTX was transferred also to the testis in male "kusatora".
