External secretion of tetrodotoxin from puffer fishes stimulated by electric shock

External secretion of tetrodotoxin from puffer fishes stimulated by electric shock 227 87 87 2 2 M. Kodama T. Ogata S. Sato Laboratory of Marine Biological Chemistry, School of Fisheries Sciences Kitasato University Sanriku 022-01 Iwate Japan Abstract Four toxic species of puffers ( Takifugu pardalis, T. poecilonotus, T. vermicularis and T. niphobles ) secreted large amounts of tetrodotoxin into the surrounding water immediately after being stimulated by electric shock. The total amount of toxin secreted ranged from 2 000 to 50 000 MU depending upon the specimen. The amount of toxin secreted seemed to be related to the toxicity of individuals. Non-toxic specimens of T. rubripes did not secrete any toxin. The stimulation always caused inflation of puffers, and this is generally accepted as a repelling behavior of these species. The secreted tetrodotoxin may act as a repellent to predators. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Marine Biology Springer Journals
