Tetrodotoxin (TTX) is a natural product that has been isolated not only from pufferfish, but also octopuses, crabs, shellfish, frogs, newts, and other aquatic animals (see below). [12] It is a potent neurotoxin that shuts down electrical signaling in nerves ; it acts via interaction with components of the sodium channels in the cell membranes ...

Species of puffer fish (the family Tetraodontidae) are the most poisonous in the world, and the second most poisonous vertebrate after the golden dart frog.The active substance, tetrodotoxin, found in the internal organs and sometimes also the skin, paralyzes the diaphragm muscles of human victims, who can die from suffocation.
The skin, liver, gonads, and intestines of the map puffer should not be consumed, as they contain high concentrations of the tetrodotoxin. [5] Specialized training is required to prepare a puffer fish containing tetrodotoxin for consumption, as to not contaminate the edible flesh with tetrodotoxin contained within the fish’s skin and organs.
Vibrio alginolyticus is a Gram-negative marine bacterium. [1] [2] It is medically important since it causes otitis and wound infection. [1]It is also present in the bodies of animals such as pufferfish, where it is responsible for the production of the potent neurotoxin, tetrodotoxin.
