Scorpions to many are looked at as the creepiest of crawlers, well known for their eight legs, grasping pincers, and most notoriously, the narrow tail that curls over its back, with a venomous stinger at the end. Some sizes of scorpions range from about 9 to 20 cm long. The scorpion's history of evolution dates back to about 430 million years ago, where today they are found all over the world. Surprisingly, only 25 of the 1750 species of scorpions are known to have venom that is capable of actually killing a human, however genetic studies have shown that this might change.
What Helps Them Creepily Crawl?
All scorpions have eight legs, a tiny claw attached to each. They have a hard exoskeleton along with a poisonous stinger at the tip of its tail. However unlike other arachnids, scorpions also have two large pincers at the front which are used to grasp and subdue their prey. Tiny hairs that act as feelers protrude from the exoskeleton, which helps them detect touch, temperature changes, and other vital information for survival. The bottom of the scorpion's body also contains comb-like sensors to further participate in its survival. Because the scorpion's exoskeleton is so thick and durable, it provides good protection from predators. Scorpions have two eyes on the top of the cephalothorax and about two to five pairs along the from corners. However the position of the eyes on the cephalothorax depends on the hardness or softness of the soil that is their environment.
