Tetrodotoxin (TTX) is a potent neurotoxin.Its name derives from Tetraodontiformes, an order that includes pufferfish, porcupinefish, ocean sunfish, and triggerfish; several of these species carry the toxin.
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 .
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.
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 .
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.

PSP affects those who come into contact with the affected shellfish by ingestion. [1] The toxins responsible for most shellfish poisonings—mainly saxitoxin, although several other toxins have been found, such as neosaxitoxin and gonyautoxins I to IV—are water-insoluble, and heat- and acid-stable.
Like other pufferfish, it can inflate itself with water or air. It forages for its preferred foods— molluscs and crustaceans —in sand and mud of the bottom sediment . Often an unwanted catch by anglers, the smooth toadfish is highly poisonous because of the tetrodotoxin present in its body, and eating it may result in death.
