While on vacations in south of France, we found a small scorpion (Euscorpius flavicaudis) and a spider (Araneus Diadematus). We put them together in a glass dish, with no escape, time for us to capture some action.
We can see scorpion sting in action around 3'21", but spider took probably some more...
Both of them were separated just after the last shot, and released in nature.
Music is "Croquis et agaceries d'un gros bonhomme en bois", from Erik Satie, played by Anne Queffélec.
