- 1. Invertebrate zoology is the study of animals that lack a vertebral column, including more than 95% of all animal species. This field encompasses a wide range of fascinating creatures such as insects, worms, mollusks, and arachnids. Invertebrates play crucial roles in ecosystems, contributing to biodiversity and serving as food sources for many other organisms. Researchers in invertebrate zoology study their anatomy, physiology, behavior, evolution, and ecological interactions to better understand these diverse and important creatures.
