“Arthropoda is the largest phylum in the world. Should all of these creatures really be classified together under one group? Why or why not?” 

Arthropoda describes the class of insects (both winged and land dwelling) and all arachnids. If you think that insects classify as  just common flies, cockroaches, and ants, you would be gravely mistaken. Insects on our planet currently, include about 400,000 types of beetles, 20,000 types of bees, 3,500 types of mosquitos, 20,000 types of butterflies, 12,000 types of ants, 900 types of crickets—I could go on and on. There are a lot of insects and spider species and they all have different things in common. The question is should there be such a broad term for so many different creatures? I used to think not. So many different creatures under the same category? That’s so confusing! But it does make labeling easier, the public isn’t that interested in insects, and in general, they just want to get rid of them. Plus, as much as these Arthropoda have differences, they have similarities too! For example, they have all of their important organs on the top part of their bodies. Picture a person doing a crab walk, that’s how the inside of one of these little guys looks like. Although different in many ways, it all boils down to how they are created and how they act and look. So, after learning more about them, I’d agree that they all belong under the same category.
