Allright, Crab, go to the Imposter. Even with eight legs, they are so well coordinated that they can move gracefully around their web or run quickly across the ground. The first part, called the prosoma, is like our head in that it contains the spider's eyes and mouth. The second body part is called the abdomen. The fluid that becomes the silk for making webs is produced in the spider's abdomen.
Some animals have special arm-like structures called pedipalps.
The structures are like our arms in that they are used to handle food and for cleaning. Spiders have plain pedipalps that end in a stub. Spiders never have large pincers at the end of their pedipalps, although they do have small claws on their stubs. Look carefully at the contestants. Remember, if the pedipalp ends in a pincer, the animal is not a spider.
