Insects Arachnids
Insects and arachnids are small invertebrate animals characterized by their six legs, segmented bodies, and exoskeletons. Insects typically have three body segments (head, thorax, and abdomen) and may have wings, while arachnids have two body segments (cephalothorax and abdomen) and eight legs. Both groups play important roles in ecosystems as predators, prey, and pollinators.
