从幼体阶段开始，海洋河豚如东方鲀含有河豚毒素（TTX），这是一种非常有效的神经毒素。虽然在这些鱼的成年鱼和幼鱼中检测到高浓度的TTX，但毒素的来源仍不清楚。在这里，我们表明，TTX在扁形虫Planocera multitactaculata有助于在整个生命周期的扁形虫的河豚鱼。建立了扁虫种特异性PCR检测方法，并在野生河豚鱼成虫的鳃中检测到特异性DNA片段。捕食实验表明，河豚鱼幼鱼可捕食扁形虫幼虫，摄食后第2天河豚鱼体内TTX含量为20-50 μg/g。捕食实验还发现，河豚鱼幼鱼也会捕食扁虫成虫，摄食两天后，河豚毒素在河豚鱼的皮肤、肝脏和肠道中积累。
Beginning with the larval stages, marine pufferfish such as Takifugu niphobles contain tetrodotoxin (TTX), an extremely potent neurotoxin. Although highly concentrated TTX has been detected in adults and juveniles of these fish, the source of the toxin has remained unclear. Here we show that TTX in the flatworm Planocera multitentaculata contributes to the toxification of the pufferfish throughout the life cycle of the flatworm. A species-specific PCR method was developed for the flatworm, and the specific DNA fragment was detected in the digesta of wild pufferfish adults. Predation experiments showed that flatworm larvae were eaten by the pufferfish juveniles, and that the two-day postprandial TTX content in these pufferfish was 20–50 μg/g. Predation experiments additionally showed flatworm adults were also eaten by pufferfish young, and after two days of feeding, TTX accumulated in the skin, liver and intestine of the pufferfish.
