Across
- 3. A hard external skeleton that provides support and protection for arthropods, made primarily of chitin.
- 6. A subphylum of arthropods characterized by having chelicerae, including spiders, scorpions, ticks, and horseshoe crabs.
- 7. eyes Eyes composed of multiple individual visual units called ommatidia, found in many arthropods, providing a wide field of view and detecting motion.
- 9. The process of shedding the exoskeleton to allow for growth in arthropods, often accompanied by the formation of a new, larger exoskeleton.
- 11. Jaw-like mouthparts found in many arthropods used for chewing and manipulating food.
- 12. Appendages located behind the mandibles in many arthropods, often involved in manipulating food or aiding in feeding.
Down
- 1. The fused head and thorax region found in many arthropods such as crustaceans and arachnids.
- 2. Respiratory organs found in some arachnids, consisting of parallel folds resembling the pages of a book, allowing for gas exchange.
- 4. The posterior body region of arthropods, typically housing internal organs and often bearing appendages or structures for various functions.
- 5. A phylum of invertebrate animals characterized by their jointed limbs and segmented bodies, including insects, crustaceans, arachnids, and myriapods
- 8. Sensory appendages found on the heads of many arthropods, used for detecting stimuli such as touch, smell, and taste.
- 10. system A respiratory system found in insects and some other arthropods, consisting of a network of tubes (tracheae) that deliver oxygen directly to tissues.
