In fact there are enough toxins in one puffer fish to kill 30 full grown adult humans, and there is not an antidote for treating this if you were to come between a puffer fish in the ocean. This deadly poison can also be used against any predators in the ocean as well. The population has never really reached extinction ever because of its deadly shield of poisons and spikes on the outer part of it body. Also in some places eating puffer fish is a delicacy and only the best chefs in the world are able to cook it and prepare it properly otherwise it could be fatal for the consumer. Many have died from taking this risk but it is worth it sometimes for many people that are brave enough to risk their life for a nice meal.
