Unit 6 study guild

1. — A fold of skin in molluscs that makes the shell or helps with breathing/moving.
4. — Sticky cells on comb jellies' tentacles (they catch prey without stinging).
5. — Phylum for jellyfish, corals, sea anemones (animals with stinging cells).
7. — Stinging cells in Cnidarians that shoot out like harpoons to catch prey or defend.
9. — Phylum name for sponges (simple animals with holes all over).
14. — No symmetry at all (body looks different on all sides), like most sponges.
17. — The attached, tube-like form of Cnidarians (like sea anemones or coral polyps).
18. — Hard outer shell on arthropods (like crabs) that protects and supports the body.
19. symmetry — Body parts arranged like a wheel around a center (top and bottom same), like jellyfish or sea anemones.

1. — The free-swimming, bell-shaped form of Cnidarians (like jellyfish).
2. — A ring or crown of tiny tentacles around the mouth in some animals (like bryozoans or brachiopods) used to catch food particles.
3. — Phylum for comb jellies (gel-like animals with rows of beating hairs).
6. — Any animal without a backbone (no spine inside).
8. — Special cells in sponges that look like tiny whips and help pull in food and water.
10. — A rough, tongue-like part in many molluscs used like a file or scraper to eat.
11. — How an animal's body parts are arranged (like mirror images).
12. symmetry — Body has a left and right side that are mirror images, like worms or squids.
13. — Tiny sharp spikes in sponges that give support and protection (made of glass-like stuff or calcium).
15. — Tube in squids/octopuses that shoots water out for jet propulsion (fast swimming).
16. sac — Organ in squids that releases dark ink to confuse predators and escape.
