Compare the protonephridium, metanephridium, a leeche's excretory system and an insect's/spider's Malpighian.
...
Contrast the protonephridium, metanephridium, a leeche's excretory system and an insect's/spider's Malpighian.
...
Which (if any) of protonephridium (e.g. from a turbellarian), a typical metanephridium (e.g. polychaete), the excretory system of a leech, and the Malpighian tubules of an insect and of a spider have a common evolutionary origin as excretory structures?

Describe movements in the major annelid groups: surface crawling in polychaetes, burrowing in oligochaetes, and "inch-worming" in hirudineans. Be sure to address: means of attaching to substrate, muscles employed, and the role of parapodia, setae, and the coelom.

Describe and draw a polychaete that is a surface-dwelling raptorial feeder.Describe and draw a tube-dwelling suspension feeder that lives in oxygen-deprived water.Compare a polychaete that is a surface-dwelling raptorial feeder's and a tube-dwelling suspension feeder that lives in oxygen-deprived water's feeding structures, setae, parapodia, and structures used for gas exchange.Contrast a polychaete that is a surface-dwelling raptorial feeder's and a tube-dwelling suspension feeder that lives in oxygen-deprived water's feeding structures, setae, parapodia, and structures used for gas exchange.Why might segmentation be reduced in a tube dwellerDraw and label a compound eye.What arthropod groups possess compound eyes?How do appositional and superpositional eyes differ?How do these differences affect their performance?What is special about the eyes of stomatopods?Describe four different uses for thoracic appendages seen in different crustaceans. Use specific examples (name the corresponding taxonomic group).Relate the morphology of the thoracic appendages seen in different crustaceans to its function. Use specific examples (name the corresponding taxonomic group).Describe the feeding biology of centipedes, spiders, mites and beetles.Compare the feeding biology of centipedes, spiders, mites and beetles with the sexual biology.Contrast the feeding biology of centipedes, spiders, mites and beetles with the sexual biology.How might differences in feeding relate to differences in mating behavior of centipedes, spiders, mites and beetles?Myriapods, branchiopods and remipedes have all been considered possible sister groups to the insects. What similarities do insects share with each of these three groups, respectively?How do ecological scenarios for how and when insects moved on to land differ among myriapods, branchiopods and remipedes?Which of these groups (myriapods, branchiopods and remipedes) appears to be closest to insects based upon DNA sequence data?Define "eusociality"Explain, in genetic terms, why eusociality is especially prevalent in ants.Give an example of division of labor among ants.Name two invertebrate groups other than the Hymenoptera which include eusocial species.Describe the respiratory structures use by onychophorans, spiders, horseshoe crabs, terrestrial isopods, myriapods, and insects.Compare the respiratory structures use by onychophorans, spiders, horseshoe crabs, terrestrial isopods, myriapods, and insects.Contrast the respiratory structures use by onychophorans, spiders, horseshoe crabs, terrestrial isopods, myriapods, and insects.Which of the respiratory structures use by onychophorans, spiders, horseshoe crabs, terrestrial isopods, myriapods, and insects are homologous structures?Which of the respiratory structures use by onychophorans, spiders, horseshoe crabs, terrestrial isopods, myriapods, and insects are convergent structures?Name and explain four factors that may have contributed to the enormous species diversity of insects.With four factors that may have contributed to the enormous species diversity of insects as context, why might spider diversity be modest in comparison?
