Its name derives from Tetraodontiformes, an order that includes pufferfish, porcupinefish, ocean sunfish, and triggerfish; several of these species carry the toxin. Although tetrodotoxin was discovered in these fish, it is found in several other animals (e.g., in blue-ringed octopuses, rough-skinned newts, and moon snails).
The standard treatment is to support the respiratory and circulatory systems until the poison is metabolized and excreted by the victim's body. [9] Researchers have determined that a fugu's tetrodotoxin comes from eating other animals infested with tetrodotoxin-laden bacteria, to which the fish develops insensitivity over time. [10]
While chiri is much more likely to cause death, sashimi fugu often causes intoxication, light-headedness, and numbness of the lips. [25] Pufferfish tetrodotoxin deadens the tongue and lips, and induces dizziness and vomiting, followed by numbness and prickling over the body, rapid heart rate, decreased blood pressure, and muscle paralysis.

Other potential causes such as paralytic shellfish poisoning (PSP), neurotoxic shellfish poisoning (NSP), scombrotoxin fish poisoning, and pufferfish poisoning should be excluded.

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.
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.
