Scorpion is very similar to scorpion in appearance. But there is a slender flagella at the end of scorpion abdomen, so Scorpion is also called tail flagella.
Scorpions have no comb-like protrusions under their abdomen and no stingers at the ends. Scorpion's limbs are particularly thick and have strong spines, so it is the main predation tool. The first pair of feet are slender and specially used as tools for exploration. When it is disturbed, the base of the tail whip will spray liquid with strong acetic acid taste. The carapace of the head and chest can be divided into three parts: front, middle and back, without eyes. The three segments of the claw limb protrude forward, and the feet must be indistinguishable before walking. The first foot is for touching, and the other three pairs are for walking.
Supplementary note: whipping scorpions ≠ whipping spiders. Scorpion has a tail, but spider has no tail. Spider's forelegs are slender, while scorpion's forelegs are thick and curved.
