What is Ostreidae?
{{Taxobox | name = True Oysters | image =Crassostrea_gigas_p1040847.jpg | image_caption = [[Pacific oyster]], ''Crassostrea gigas'' | regnum = [[Animal]]ia | phylum = [[Mollusk|Mollusca]] | classis = [[Bivalvia]] | ordo = [[Ostreoida]] | familia = '''Ostreidae''' | familia_authority = [[Rafinesque]], 1815 }} '''Ostreidae''' are the '''true oysters'''. The family includes most [[species]] eaten under the name ''[[oyster]]''. [[Pearl oyster]]s are not true oysters because they belong to a different order, the [[Pterioida]]. Like [[scallop]]s, true oysters have a central [[adductor muscle]]. This causes a [[scar]] in the middle of the [[Animal shell|shell]]. It is the point of attachment. The shell is often irregular because oysters attach to [[substrate]]s. ==Other websites== {{wikispecies-inline|Ostreidae}}<br/> {{commonscat-inline|Ostreidae}} {{biology-stub}} [[Category:Bivalves]]
