2. lungs: Respiratory organs found in some arachnids, consisting of parallel folds resembling the pages of a book, allowing for gas exchange.
4. Jaw-like mouthparts found in many arthropods used for chewing and manipulating food.
6. A class of arthropods characterized by having six legs, typically three body segments (head, thorax, abdomen), and often wings, including beetles, flies, ants, and butterflies.
9. A diverse group of arthropods primarily aquatic, including crabs, lobsters, shrimp, and barnacles, typically possessing two pairs of antennae and biramous appendages.
11. Sensory appendages found on the heads of many arthropods, used for detecting stimuli such as touch, smell, and taste.
14. system: A respiratory system found in insects and some other arthropods, consisting of a network of tubes (tracheae) that deliver oxygen directly to tissues.
15. The process of shedding the exoskeleton to allow for growth in arthropods, often accompanied by the formation of a new, larger exoskeleton.
16. A subphylum of arthropods including centipedes and millipedes, characterized by having numerous body segments and multiple pairs of legs.
17. A hard, protective shell covering the dorsal side of some arthropods, particularly crustaceans like crabs and lobsters.
18. Paired appendages found on the rear segments of many arthropods, serving various functions such as sensing vibrations, detecting predators, or aiding in navigation.

1. The scientific study of arthropods, encompassing their biology, ecology, behavior, and evolution.
3. Paired appendages found on the abdomen of many crustaceans, used for swimming, reproduction, and sometimes respiration.
5. A hard external skeleton that provides support and protection for arthropods, made primarily of chitin.
7. A class of arthropods characterized by having eight legs, including spiders, scorpions, ticks, and mites.
8. The fused head and thorax region found in many arthropods such as crustaceans and arachnids. Abdomen: The posterior body region of arthropods, typically housing internal organs and often bearing appendages or structures for various functions.
10. A phylum of invertebrate animals characterized by their jointed limbs and segmented bodies, including insects, crustaceans, arachnids, and myriapods.
12. Appendages located behind the mandibles in many arthropods, often involved in manipulating food or aiding in feeding.
13. A subphylum of arthropods characterized by having chelicerae, including spiders, scorpions, ticks, and horseshoe crabs.
19. eyes: Eyes composed of multiple individual visual units called ommatidia, found in many arthropods, providing a wide field of view and detecting motion.
