What is Aspidogastrea?
{{Taxobox | name = Aspidogastrea | regnum = [[Animal]]ia | phylum = [[Platyhelminthes]] | classis = [[Trematoda]] | subclassis = '''Aspidogastrea''' }} The '''Aspidogastrea''' (gr. ''aspid'' - shield, ''gaster'' - stomach/pouch) is a small group of [[fluke]]s. There are about 80 [[species]]. The group is a [[Subclass (biology)|subclass]] of the [[Trematoda]], and sister group to the [[Digenea]]. Species are between approximately one mm to several cm long. They are [[parasite]]s of [[freshwater]] and [[ocean|marine]] [[mollusc]]s and [[vertebrate]]s ([[Chondrichthyes|cartilaginous]] and [[Actinopterygii|bony]] [[fish]]es and [[turtle]]s). Maturation may occur in the [[mollusc]] or [[vertebrate]] host. None of the species has any [[economic]] importance, but the group is of very great interest to [[biologist]]s because it has several characters which appear to be [[basal]]. == Other websites == *[http://tolweb.org/tree?group=Aspidogastrea&contgroup=Platyhelminthes Aspidogastrea from Tree of Life] {{Webarchive|url=https://web.archive.org/web/20121028112658/http://tolweb.org/tree?group=Aspidogastrea&contgroup=Platyhelminthes |date=2012-10-28 }} *[http://erms.biol.soton.ac.uk/lists/brief/Aspidogastrea.shtml Checklist of European aspidogastreans] {{Webarchive|url=https://web.archive.org/web/20041012185338/http://www.erms.biol.soton.ac.uk/lists/brief/Aspidogastrea.shtml |date=2004-10-12 }} *[http://www.fishdisease.net Fishdisease.net] {{Webarchive|url=https://web.archive.org/web/20071015033911/http://www.fishdisease.net/ |date=2007-10-15 }} {{biology-stub}} [[Category:Flatworms]]
