(Sharknado) What made the sharks so blood thirsty, as compared to regular sharks?
gpt
As we all know sharks have an extremely keen sense of smell. It's their main tool for locating and hunting prey, and it's often said that a shark can detect a drop of blood a mile away. Have you ever tried to smell something underwater? It's very difficult. But a shark can do it, no sweat. That's how good they are at smelling things. 

Now, transport that shark from the water to a tornado. Smelling things in the wind is much easier, and suddenly the shark is overwhelmed by the scent of prey animals all around him. What's more, he's disoriented by the swirling wind and can't make out the direction the scents are coming from. All of this overstimulus throws the shark into a blood fury that cannot be sated. They become very dangerous and the result is a classic sharknado situation.
