Arthropods are a diverse group of invertebrate animals characterized by their segmented bodies, exoskeletons, and jointed appendages. This group includes familiar creatures such as insects, arachnids (like spiders and scorpions), and crustaceans (such as crabs and lobsters). They are the largest phylum in the animal kingdom, with millions of species identified. Arthropods play crucial roles in ecosystems, serving as pollinators, decomposers, and a food source for other animals. Their adaptability allows them to thrive in various environments, from deep oceans to high mountains. The study of arthropods is essential for understanding biodiversity and ecological balance.
