Arthropods are a diverse group of invertebrate animals that make up the largest phylum in the animal kingdom. They include insects, spiders, crustaceans, and myriapods. Arthropods are characterized by their jointed limbs, segmented bodies, and exoskeletons made of chitin. Research on arthropods encompasses a wide range of topics, including their evolutionary history, ecology, behavior, physiology, and interactions with other organisms. Scientists study arthropods to understand their unique adaptations, their roles in ecosystems, and their relationships with humans (including as pests or beneficial species). Arthropods are of significant interest to researchers in fields such as entomology, ecology, evolutionary biology, and pest management. By studying arthropods, scientists can gain insights into the diversity and complexity of the natural world and develop strategies for conserving biodiversity and managing pest populations.
