Across
- 3. Paired appendages found on the rear segments of many arthropods, serving various functions such as sensing vibrations, detecting predators, or aiding in navigation.
- 4. Appendages located behind the mandibles in many arthropods, often involved in manipulating food or aiding in feeding.
- 6. eyes: Eyes composed of multiple individual visual units called ommatidia, found in many arthropods, providing a wide field of view and detecting motion.
- 8. Jaw-like mouthparts found in many arthropods used for chewing and manipulating food.
- 9. Paired appendages found on the abdomen of many crustaceans, used for swimming, reproduction, and sometimes respiration.
- 11. Sensory appendages found on the heads of many arthropods, used for detecting stimuli such as touch, smell, and taste.
- 12. 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.
- 13. A subphylum of arthropods characterized by having chelicerae, including spiders, scorpions, ticks, and horseshoe crabs.
- 16. A phylum of invertebrate animals characterized by their jointed limbs and segmented bodies, including insects, crustaceans, arachnids, and myriapods.
- 18. A subphylum of arthropods including centipedes and millipedes, characterized by having numerous body segments and multiple pairs of legs.
- 19. lungs: Respiratory organs found in some arachnids, consisting of parallel folds resembling the pages of a book, allowing for gas exchange.
Down
- 1. A class of arthropods characterized by having eight legs, including spiders, scorpions, ticks, and mites.
- 2. system: A respiratory system found in insects and some other arthropods, consisting of a network of tubes (tracheae) that deliver oxygen directly to tissues.
- 5. The posterior body region of arthropods, typically housing internal organs and often bearing appendages or structures for various functions.
- 7. A diverse group of arthropods primarily aquatic, including crabs, lobsters, shrimp, and barnacles, typically possessing two pairs of antennae and biramous appendages.
- 10. A hard external skeleton that provides support and protection for arthropods, made primarily of chitin.
- 13. The fused head and thorax region found in many arthropods such as crustaceans and arachnids.
- 14. The scientific study of arthropods, encompassing their biology, ecology, behavior, and evolution.
- 15. A hard, protective shell covering the dorsal side of some arthropods, particularly crustaceans like crabs and lobsters.
- 17. The process of shedding the exoskeleton to allow for growth in arthropods, often accompanied by the formation of a new, larger exoskeleton.
