Vocabulary:
1. invertebrate: animals that don’t have backbones
2. ganglion: mass of nerve cells
3. gut: digestive tract
4. coelom: body cavity that contains the internal organs
5. open circulatory system: circulatory system in which the fluid is not contained entirely within vessels
6. closed circulatory system: circulatory system in which a heart circulates blood through vessels in a closed loop
7. segment: identical or almost identical repeating body part
8. exoskeleton: hard external supporting structure
9. compound eye: an eye composed of many light detectors
10. antenna: a feeler that senses touch, taste, or smell
11. metamorphosis: phase in life cycle of many animals during which a rapid change from immature to adult form takes place
12. endoskeleton: an internal skeleton made of bone or cartilage
13. water vascular system: system of canals filled with watery fluid that circulates through an echinoderm’s body
14. bilateral symmetry: type of symmetry where two sides of the body mirror each other
15. radial symmetry: type of symmetry where the body is organized around the center like spokes on a wheel
16. asymmetry: having no symmetry
17. cnidarians: invertebrate group that has stinging cells
18. flatworms: invertebrate group that includes the simplest of worms, such as planarians
19. mollusks: invertebrate group with soft bodies, such as octopus and snails
20. annelid worms: invertebrate group often called the “segmented worms”
21. arthropods: invertebrate group whose name means “jointed limb”
22. echinoderms: invertebrate group with a spiny internal skeleton, such as sea stars
23. mandibles: mouthparts of an arthropod that can pierce and chew food
24. cephalothorax: body part made of both head and thorax in an arachnid
25. nerve ring: circle of nerve fibers in an echinoderm
26. collar cells: special cells in sponges that filter and digest food from the water
27. radula: organ in a mollusk used to scrape food
28. mantle: layer of tissue in a mollusk that protects the body
29. visceral mass: gills, guts, and other organs in a mollusk
30. shell: part of the mollusk body that protects it from predators and keeps it from drying out
