In their natural environment, puffer fish have a toxin. The toxin is called tetrodotoxin, or more precisely anhydrotetrodotoxin 4-epitetrodotoxin and is about 1200 times deadlier than cyanide. This poison can also be found in other animals such as the Blue-Ringed Octopus, or even some newts. The pufferfish does not create the poison itself; rather it is generated by various genera of bacteria within the fish. 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 tissues from a toxin-producing fish. Also, some fish are more poisonous than others. A poisonous fish has enough poison to kill 30 adults.
Tetrodotoxin is a very potent neurotoxin and shuts down electrical signaling in nerves by binding to the pores of sodium channel proteins in nerve cell membranes. It does not cross the blood-brain barrier, leaving the victim fully conscious while paralyzing the remainder of the body. In animal studies with mice, 8 µg tetrodotoxin per kilogram of body weight killed 50% of the mice (see also LD50). The pufferfish itself has immunity to the poison due to a mutation in the protein sequence of the sodium channel pump on the cell membranes.
Yes, the puffer fish still has the toxin if it is dead.

a puffer fish is edible but its really much risky.First you must take out all the organs of the fish because thats where the poison is actually is u must wash it carefully many times. If u touch it it wont harm u ...not as much anyways.
A puffer fish is quite interesting dont u think?

Absolutely, an animal doesn't stop being poisonous when its dead. Mind you I wouldn't want to find out.

Many parts of the fish like liver,muscles, skin and ovaries contain poison deadlier than cyanide- there is no antidote known. Japanese used to eat it and many have died.

Yes, the poison kills THOUSANDS of people in japan because sometimes the chefs make it wrong

Yes. The meat of the fish is not, but it has sacks of venom that will remain toxic.

yes poison is still in his blood stream

More so as the venom is released into all of it's tissues by cellular decay.

yes that's why people die when they eat it. Most poisionous animals remain poisionous postmortem.
