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]
Other potential causes such as paralytic shellfish poisoning (PSP), neurotoxic shellfish poisoning (NSP), scombrotoxin fish poisoning, and pufferfish poisoning should be excluded. [ 1 ] The reversal of hot and cold sensations is an occasional symptom of CFP that may help differentiate it from norovirus .
Deflated Valentinni's sharpnose puffer. Tetraodontidae is a family of marine and freshwater fish in the order Tetraodontiformes.The family includes many familiar species variously called pufferfish, puffers, balloonfish, blowfish, blowers, blowies, bubblefish, globefish, swellfish, toadfish, toadies, toadle, honey toads, sugar toads, and sea squab.

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.
They are sometimes collectively called pufferfish, [3] not to be confused with the morphologically similar and closely related Tetraodontidae, which are more commonly given this name. They are found in shallow, temperate, and tropical seas worldwide.
Pseudoalteromonas tetraodonis is a marine bacterium isolated from the surface slime of the puffer fish. It secretes the neurotoxin , tetrodotoxin . [ 2 ] It was originally described in 1990 as Alteromonas tetraodonis but was reclassified in 2001 to the genus Pseudoalteromonas .
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.
