Habitat

Biome: Freshwater [1].

Ecology: This is a freshwater non migratory species found in coastal streams and lakes and occurs in silt , sand , and gravel substrates (Clarke 1981, Nedeau et al. 2000).

Host fish for the glochidial include the alewife (Alosa pseudoharengus) (Clarke 1981), white sucker (Catostomus commersoni), threespine stickleback (Gasterosteus aculeatus), pumpkinseed (Lepomis gibbosus), and white perch (Morone americana) (Davenport and Warmuth 1965, Wiles 1975).[1].

Name Status: Accepted Name .

Last scrutiny: 17-Oct-2001

Recently, Zanatta et al. (2007) supported the monophyly of both Pyganodon and Utterbackia using mutation coding of allozyme data . The Eurasian Anodonta cygnea was resolved as the sister of the remaining ingroup taxa, including Pyganodon, Utterbackia, and the North American Anodonta. Graf and Cummings (2007) placed implicata in Pyganodon along with other eastern North American taxa; lacustris, grandis, fragilis, cataracta and gibbosa. Anodonta was restricted to western North American and Eurasian species. This indicates that futher phylogenetic analysis of the Anodontinae is required including both North American and Eurasian species. There has been some suggestion that the name Anodonta atra (Rafinesque, 1820) has priority over Anodonta implicata based on two characters from the description of A. atra. However, A. atra was described without illustration and with limited descriptive characters attributable to other Anodonta and Pyganodon species. Graf and Cummings (2007) placed atra in cataracta. With such limited information, there is insufficient evidence to justify replacing the name at this time to atra.

A list of synonyms for this species can be found on The MUSSEL project web site (Graf and Cummings 2011).[1].
