10. What are some features of phylum Platyhelminthes? What features do we see in classes Trematoda and Cestoidea that fit with their parasitic lifestyles? 11. What are some features of phylum Nematoda? What is ecdysis, and what other phylum also has this feature? What are some ways that nematodes obtain nutrition? 12. There are quite a few different types of "worms" in the world! How would you distinguish annelid, platyhelminth, and nematode worms from one another? 13. What are some features of Phylum Arthropoda? What are features of the main clades we discussed (Chelicerates, Crustacea, Hexapoda, Myriapoda)? Which phyla are primarily aquatic, and which are terrestrial? What arthropod features were important for the transition from ocean to land? What features contributed to the diversification of insects? Be familiar with the following: chelicerae, pedipalps, uniramous and biramous appendages, mandibles, metamorphisis, trachea. 14. What other invertebrate groups (besides arthropods) have made the transition to land? What adaptations do these groups have to life on land? 15. What are some features of phylum Echinodermata? What are methods echinoderms use to obtain nutrition? Be familiar with the following: endoskeleton, water-vascular system, tube feet. 16. What are some features of phylum Chordata? Do all chordates have vertebrae (i.e. a backbone)? How do the invertebrate chordates obtain nutrition?.
