Look carefully at the contestants. Remember, if the pedipalp ends in a pincer, the animal is not a spider. Scorpion, go off to the side. Now we are down to two contestants. While it is a bit technical, clue number 5 is also very important.
Spiders have special mouth parts, or jaws, called chelicerae, that look like farngs.
Chelicerae can move like a lobster's pincers. Poison comes out of them, and spiders use their chelicerae to kill their prey. Examine the mouths of our two contestants carefully. Obviously we need a magnifying lens. Contestants, hold up your magnifying lenses.
