Poisonous fish

Puffer fish are the most poisonous fish in the world.

Poisonous fish are fish that are poisonous to eat. They contain toxins which are not destroyed by the digestive systems of animals that eat the fish.[1] Venomous fish also contain toxins, but do not necessarily cause poisoning if they are eaten, since the digestive system often destroys their venom.[1]
