Anatomy of a Scorpion
You might have noticed that scorpions have some of the same characteristics as a lobster or crab. Their pinchers are one of the similar features. It might not surprise you that both scorpions and lobsters are in the same group. They are both part of the Phylum Arthropoda. What might surprise you is scorpions are even more closely related to spiders. Both are part of the subgroup (Class) Arachnida. If you do some research, you will find that these animals share common characteristics, such as having eight legs. This is unlike insects that have six legs. This means that scorpions are not insects. However, insects are their favorite food.
The anatomy of a scorpion has some similar characteristics to other arthropods, such as lobsters and crabs. They also have similar features to spiders and other arachnids. Just count the number of legs and you will see how they match the number of legs found on spiders. Click image to enlarge.
