👉 Crustaceology is a branch of entomology that focuses on the study of crustacean species, including crabs, snails, and other aquatic animals. It is often used to describe the diversity of creatures found in oceans, lakes, rivers, and other bodies of water. Crustaceological studies can include the identification, classification, taxonomy, morphology, ecology, behavior, physiology, evolution, biogeography, and conservation of these species.
