Over the years, literally hundreds of people have told me that spiders are not animals. This seems to happen the majority of the times that the topic of spiders comes up in conversation. When I reply that spiders are, in fact, animals, the usual response is “Spiders are insects!” This gives me headaches, because (1) spiders aren’t insects, and (2) insects are also animals.
Spiders happen to be my favorite animal, so this is quite confusing to me. Hopefully, this screenshot from my Google-search for “animal definition” will help spread the word that spiders are, indeed, part of the animal kingdom.
