It's sunny today. In science class, we learned about animal classification, which included groups like amphibians and arthropods. Shockingly, there are three different types of worms: flatworms, roundworms, and segmented worms. These aren't insects! Many of these worms can live inside other animals, including humans. Nematodes, a type of roundworm, can be parasites in livestock and even in humans. Learning about this has given me the creeps. I might have nightmares tonight.
