Tetrodotoxin is a highly potent neurotoxin found in certain marine animals, such as pufferfish. As little as 1 to 2 milligrams of tetrodotoxin can be lethal to humans, depending on individual sensitivity and body weight. The toxin blocks sodium channels in nerves, leading to paralysis and potentially fatal respiratory failure. Due to its potency, even a tiny amount can be dangerous, making it crucial to avoid consumption of improperly prepared seafood known to contain the toxin.

Tetrodotoxin is a potent neurotoxin found primarily in certain species of pufferfish. To obtain it, pufferfish must be carefully harvested, as the toxin is concentrated in their organs, particularly the liver, ovaries, and skin. It is crucial to handle the fish with extreme caution and to follow strict safety protocols, as even small amounts of tetrodotoxin can be lethal. However, extracting and using tetrodotoxin is highly regulated and illegal in many regions due to its toxicity.
Tetrodotoxin contains a series of carbon-carbon and carbon-oxygen bonds, with a unique fused ring structure known as a tricyclic guanidinium moiety. This complex structure is responsible for the potent blocking effect of tetrodoxin on sodium channels.

Scientists have found that toxic fugu have unique exocrine glands for the secretion of tetrodotoxin. The fish appear to actively produce the toxin, rather than passively acquire it from the environment.

Tetrodotoxin is a poison. It begins with the letter t.
A Blue ring Ooctopus does have toxic called tetrodotoxin.
Puffer fish have a very strong toxin in their bodies that is called tetrodotoxin.
Tetrodotoxin binds to voltage gated sodium channels and blocks them from passing sodium into cells. These channels are a critical part of the functioning of nerve cells and blocking the movement of sodium effectively blocks the transmission of information along the nerve cells. This in turns leads to paralysis in the animal or person that was exposed to tetrodotoxin.
