Phylum Arthropoda

Phylum Arthropoda is a diverse group of invertebrate animals that includes insects, spiders, crustaceans, and millipedes. These creatures have jointed limbs, segmented bodies, and hard exoskeletons made of chitin. Arthropods are characterized by their ability to adapt to various environments, making them the most numerous and successful animal group on Earth. They play crucial roles in ecosystems as pollinators, decomposers, and as part of food webs. Common examples include ants, butterflies, crabs, and scorpions. The study of arthropods is important for understanding biodiversity and the health of natural environments.
