Tetrodotoxin
Tetrodotoxin is a potent neurotoxin found mainly in certain species of pufferfish, as well as in some other marine animals. It blocks sodium channels in nerve cells, preventing normal communication between nerves and muscles. This can lead to paralysis, respiratory failure, and potentially death if ingested in sufficient quantities. Tetrodotoxin is not degraded by cooking, making it a serious risk for those who consume poorly prepared pufferfish, a delicacy in some cultures. There is no known antidote, highlighting the importance of careful handling and preparation of these fish.

Tetrodotoxin is a potent neurotoxin found primarily in certain marine animals, such as pufferfish, as well as in some types of octopus and newts. It blocks sodium channels in nerve cells, preventing them from transmitting signals, which can lead to paralysis, respiratory failure, and even death if ingested. Despite its toxicity, some cultures delicately prepare pufferfish as a dish called fugu, requiring skilled chefs to reduce the risk of poisoning. tetrodotoxin has garnered interest in medical research for its potential therapeutic applications, highlighting the dual nature of this toxin as both dangerous and intriguing.
