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.
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 ...

The pufferfish does not create the poison itself; rather it is generated by bacteria e.g. Pseudomonas within the fish. [12] The fish obtains the bacteria by eating food containing these bacteria. Pufferfish that are born and grown in captivity do not produce tetrodotoxin until they receive some of the poison-producing bacteria, often by eating ...

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.
