对四种有毒河豚（Takifugu paradalis、T. poecilonotus、T. vermicularis和T.在受到电击刺激后，它们立即将大量的河豚毒素分泌到周围的水中。分泌的毒素总量范围为2000- 50，000 MU，取决于标本。毒素的分泌量似乎与个体的毒性有关。无毒T.红足不分泌毒素。刺激总是引起河豚的膨胀，这通常被认为是这些物种的排斥行为。分泌的河豚毒素可作为捕食者的驱避剂。
Four toxic species of puffers (Takifugu paradalis, 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 2000-50,000 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.
