Anatomy of a Scorpion

You miight 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 scropions are even closer related to spiders. Both are part of the subgroup (Class) Arachnida. If do some research you will find that these animals share common caracteristics, such as both have eight legs. This is unlike insects that have six legs. This means that scorpions are not insects. However, insects are their favorite food.
