Invertebrates (Sponges, Cnidarians, Flatworms, Roundworms, Mollusks, Arthropods, Annelids, And Echinoderms)

Front 1

bony sponge, barrel sponge
-asymmetry
-pores
-skeleton called spongin
-can digest food(filters food particles such as protists, algae, and bacteria)

Back 1

sponges

Front 2

corals, sea anemones, hydras, jellyfish(polyp/medusa)
-radial symmetry
-nerve net
-digestive tract and only one body opening(food/waste go in/come out through the same place)
-are predatory who use stinging cells to stun prey

Back 2

cnidarians

Front 3

planarians, flukes, and tapeworms
-most are parasitic
-a tapeworm doesn't have a mouth or a digestive system
-absorbs food that's digested by it's host
-bilateral symmetry
-uses cilia to move
-invertebrate

Back 3

flatworms

Front 4

heart worms and nematodes
-has bilateral symmetry
-has digestive system, mouth, and an anus
-they move by thrashing their bodies using long muscles which only allow them to move laterally
-invertebrate

Back 4

roundworms

Front 5

snails, clams, and squids
-bilateral symmetry
-invertebrates
-snails have an open-circulatory system, and squids have a closed-circulatory system
-has mouth, digestive tract, and an anus 

Back 5

mollusks

Front 6

(means "little rings") earthworms, marine worms, and leeches
-use setae to move
-has a mouth, digestive tract, and an anus
-bilateral symmetry
-segmented tube-shaped bodies
-live in freshwater, salt water, and moist soil
-have closed circulatory systems
-oxygen/CO2 exchanged through skin

Back 6

annelids

Front 7

(means "jointed foot") insects, spiders, crabs,
-bilateral symmetry
-exoskeleton
-head, thorax, and abdomen
-open circulatory system
- legs

Back 7

arthropods

Front 8

sea stars, mollusks, and sea urchins:
-move with thousands of tube feet
-has water-vascular system
- has radial symmetry
-has hard exoskeleton

Back 8

echinoderms
