This illustration depicts a dorsal view of two members of the class, Arachnida, a representative scorpion on the left, and a representative tick on the right. The scorpion is a member of the order, Scorpiones, while the tick is a member of the subclass, Acari. The important feature highlighted here, is that in the case of scorpions, the cephalothorax is separate from the abdominal region, while in ticks, the cephalothorax has become fused with the abdomen.
