Invertebrate Diversity
| Question | Answer |
|---|---|
| Class Scyphozoa | Ex: Jellies; Phylum Cnidarians |
| Class Hydrozoa | Ex: hydras, some coral animals, & large Portuguese man-of-war; Phylum Cnidarians; |
| Class Anthozoa | Ex: Sea anemones & most coral animals; Phylum Cnidarians |
| Class Turbellaria | Ex: Planarians; Phylum Platyehlmenthes; Free-living & marine, but some live in terrestrial environments |
| Class Trematoda | Ex: Flukes; Phylum Platyhelmenthes; Heteroptrophsthat absorb nutrients from body fluids of a living host and in process harm the host |
| Class Cestoidea | Ex: Tapeworms; Phylum Platyhelmenthes; live inthe digestive tracts of vertebrates |
| Group Acoelomate | Ex: Flatworms; Phylum Annelida; animals that lack a body cavity |
| Group Pseudocoelomate | Ex: Roundworms; Phylum Annelida; fluid-filled body cavity in direct contact with the digestive tract |
| Group Coelomate | Ex: Annelids; Phylum Annelida; fluid-filled cavity that is completely lined by tissue that originated in the embryo from mesoderm tissue |
| Class Hirudinea | Ex: Parasitic Leeches; Phylum Annelida |
| Class Oligochaeta | Ex: Earthworms; Phylum Annelida; tunneling through soil helps air to circulate in it, which helps plants to grow |
| Class Polychaeta | Ex: Sandworms; Phylum Annelida; includes many species, such as sandworms, that scavenge for food on the ocean floor |
| Class Gastropoda | Ex: snails & sea slugs; Phylum Mollusca; make up largest group of mollusks |
| Class Bivalvia | Ex: Clams, oysters, mussels, and scallops; Phylum Mollusca |
| Class Cephalopoda | Ex: squids & octopuses; Phylum Mollusca; faster & more agile than gastropods and bivalves |
| Class Echinoidea | Ex: Sea Urchins; Phylum Echinodermata;most spines |
| Class Ophiroidea | Ex: Brittle Stars; Phylum Echinodermata |
| Class Holothuroidea | Ex: Sea Cucumbers |
| Class Asteroidea | Ex: Sea stars |
| Protostomes (what are phylums) | Mollusks and Annelids |
| Deuterostomes (what are phylums) | Echinoderms and Chordates |
| 5 Coelomates | Mullusks, Annelids, Echinoderm, Chordates, Arthropods |
| Arthropoda (examples) | Ex: Insects, Crustaceans, Spiders |
| Order Coleoptera (most) | beetles |
| Order Lepidoptera | moths, butterflies |
| Order Diptera | Flies, Mosquitoes |
| Order Hymenoptera | Ants, Bees, Wasps |
| Porifera (ex) | Sponge |
| Cnidaria (ex) | Hydras, jellies, and anemones) |
| Platyhelminthes (ex) | Flatworms |
| Nematoda (ex) | Roundworms |
| Annelida (ex) | Segmented Worms |
| Mollusca (ex) | Snails, clams, squids |
| Echinodermata (ex) | Sea stars, sea urchins, sea cucumbers |
