The Deathstalker Scorpion: The World's Most Expensive Liquid

The Deathstalker scorpion venom is recognized as the most expensive liquid in the world. Each individual produces no more than 2 mg of venom at a time, meaning that it would take over 2 million 'milking' sessions to fill a gallon. The value of this venom lies in a key component that is used in the treatment of brain tumors. The cost for one gallon (3.7 liters) amounts to 39 million dollars.
