Anatomy

Scorpions are invertebrates, which means that they do not have a backbone. All arthropods, including scorpions, spiders, insects, and crustaceans, are defined by their exoskeletons, jointed appendages, and segmented bodies. One of the most characteristic traits of scorpions are their long tails that curl over their backs and end with a venomous stinger. A scorpion's body is divided into two main parts which are the cephalothorax and the abdomen. The cephalothorax is located at the front of the body and are where a scorpion's four pairs of legs with setae are attached to the body. The cephalothorax includes their mouth parts and two large pincers known as pedipalps. Scorpions use their pinchers to help feel out their environment, defend themselves from predators, and to aid in trapping prey. Scorpions have two eyes on top of the cephalothorax but additionally have two to five pairs of eyes on the front corners and sides of their cephalothorax. Despite having multiple pairs of eyes, scorpions do not have good vision. However, their eyes are extremely light sensitive and allow them to see well in the dark or low lighting. The posterior portion of the body is the abdomen and includes the majority of their body length and their long tail, known as the metasoma. The metasoma has 5 segments and ends with the telson, which is the venom bulb. Inside of the telson are two venom glands that send the venom to the aculeus, commonly referred to as their stinger. Only around 30 species of scorpions have venom that is fatal to humans, but scorpion stings are known to cause pain, numbness, tingling, swelling, and warmth in the affected area.

Habitat and Range

1,500 scorpion species have been classified and it is likely that there are hundreds of species yet to be discovered. Of these 1,500 different species, around 40 species live in the United States.
