Tetrodotoxin is a potent neurotoxin with no known antidote. It gets its name from "Tetraodontiforme", the name of the order of fish that carry the toxin. Tetraodontiforme includes animals such as the pufferfish, procupinefish, and ocean sunfish.
Tetrodotoxin contains both covalent and polar covalent bonds. Covalent bonds are formed between atoms sharing electrons, holding the molecule together. Polar covalent bonds have unequal sharing of electrons, creating partial positive and negative charges within the molecule, contributing to its overall structure and properties.
Plants evolved before animals.
No animals can photosynthesize. Photosynthesis is a process carried out by plants, algae, and some bacteria to convert sunlight into energy. Animals obtain energy through consuming plants or other animals.

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 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.
neurotoxins, like tetrodotoxin
A Blue ring Ooctopus does have toxic called tetrodotoxin.
Tetrodotoxin is a poison. It begins with the letter t.
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.
Tetrodotoxin blocks voltage-gated sodium channels in nerve cells, leading to the inhibition of action potentials and the disruption of nerve signal transmission. This can result in paralysis, respiratory failure, and death in severe cases.
The blue ringed octopus is smaller than a tennis ball but it is one of the most venomous animals in the world. It has a neurotoxin (tetrodotoxin) which can cause paralysis, cardiac arrest and death.If it stings an animal, such as a human, you can die.There is currently no anti-venom available.
It blocks the sodium channels that are required to create action potential in the muscles to make them contract.
