This may be easy with some orders (there may only be a few species in the entire order) or may be very challenging when there are dozens of families. In the latter case, you need to summarize the information by finding generalities among the diversity of species in the order.NOTE: if you use material from any of the resources verbatim, use quotes and cite the source; review the plagiarism rules on the syllabus.Name – what does the name mean? (Latin or Greek roots of the name)Taxonomic status – Superclass, Class, Order, number of families and genera, representative families (with common names if they exist), familiar or notable genera or species (common names ) in each family, local species (if any)Description – general description of body type, unusual characteristics; describe what particular characters link the species in this order and differentiate them from other ordersHabitat – fresh or salt water, lakes or rivers, deep or shallowDistribution – summarize the global range of the orderEcology and life history – foraging mode, unusual species or habitat interactionsAdditional details – any unusual or interesting characteristics of this order; any interaction with humans (harvested, used in aquaria, dangerous, etc.)Recent research – find and cite a paper that has been written about one or more of the species inthis orderReferences used – cite the sources you consulted to obtain your informationSuggested resources:Paxton, J.

America, Australia, New Zealand, EuropeEcology and life history: Long larval stage (ammocoetes) in freshwater streams (2-7 years), followed byshort adult stage in fresh or salt water (1 month - 2 years)Highly fecund (60,000 -300,000 eggs)Larval forms generally detritus feeders; adults may be parasitic on fish, or non-feedingParasitic species undergo metamorphosis, feed in fresh or salt water as juveniles, then return to streams as adults to spawn. Non-parasitic species are stream-resident, do not feed after metamorphosis, and spawn soon after metamorphosisParasitic form appears to be the ancestral typeSome Australian species are predatory
