Which of the following is NOT a type of vertebrate pest?

Spiders are classified as arachnids, not vertebrates. The key characteristic that distinguishes vertebrates is the presence of a backbone or spine, which is found in categories like fish, amphibians, and birds. Each of these groups has a well-developed skeletal system comprising bones, unlike spiders, which have an exoskeleton and belong to the class of invertebrates. Understanding the classifications of animals helps clarify which species are considered vertebrate pests, focusing on those with internal skeletons while excluding invertebrates like spiders.
