Puffer fish from all other sources potentially contain deadly toxins and therefore are not considered safe. The liver, gonads (ovaries and testes), intestines, and skin of some puffer fish contain the toxins tetrodotoxin and/or saxitoxin.
The puffer fish has a unique way of defense. It puffs up two times its size and also releases a toxin called tetrodotoxin. This toxin makes a very unpleasant smell and not a good meal for the predator. Tetrodotoxin is present in the liver, blood, muscle tissue, ovaries, and intestine. If a human should eat puffer fish meat they would be poisoned and taken to the hospital. REPRODUCTION: The puffer fish has a unique reproduction method. The females lay eggs at the shore after the males have pushed them to a certain place. These are spherical in shape and usually float on the surface because of their weight.
