Mactra patagonica d'Orbigny 1846

Mactra patagonica is a species of mussels in the family Mactridae. This species is extinct. They are surficial modifiers. Individuals could grow to 60 mm. They have sexual reproduction. They are facultatively mobile animals.

URI: http://eol.org/schema/terms/extinct
Definition: A taxon is Extinct when there is no reasonable doubt that the last individual has died. A \r\ntaxon is presumed Extinct when exhaustive surveys in known and/or expected habitat, \r\nat appropriate times (diurnal, seasonal, annual), throughout its historic range have failed \r\nto record an individual. Surveys should be over a time frame appropriate to the taxon’s life cycle and life form.
