Stonefish is not the kind of fish you want to eat.  It is the fish you by all means need to avoid touching it as it is the most venomous fish on the planet.

Stonefish stings have occured many times in Australia, causing poisoning and death when not treated promptly.  A person's feet can get stung when he steps on a stonefish, but less often get stung when he picks it up.

Stonefish stings can occur not only in the water, but also on the beach as stonefish can survive for up to 24 hours out of water.

Stonefish looks like a rock or coral.

Stonefish is found in coastal regions of Indo-Pacific oceans, but some species live in rivers.

Treatments for stoenfish stings include using heat to the affected area and antivenom. Hot water at a temperature no lower than 45 oC can destroy stonefish venom and in severe cases, antivenom is needed.
