Sagittunio nasutus, the eastern pondmussel, is a species of freshwater mussel in the family Unionidae, the river mussels. [2]
This species is native to the eastern United States and Ontario, Canada. [1] In Canada, the eastern pondmussel has been adversely affected by zebra mussels, which were introduced near the end of the 1980s. [3] Originally assessed as endangered due to the existence of only two known Canadian populations, [3] the eastern pondmussel was placed on Schedule 1 of the Species at Risk Act in 2013. [4] However, a reassessment by the Committee on the Status of Endangered Wildlife in Canada in 2017 identified seventeen additional subpopulations, [5] and the eastern pondmussel was relisted as "special concern" in August 2019. [4] The population of the lower Great Lakes has limited diversity in certain mitochondrial genetic markers compared to those of the eastern seaboard's population, evidence of a founder effect and suggestive of a post-glacial arrival of Atlantic coast mussels to the Great Lakes by a restricted route. [5]: 7 [6] The Walpole Island First Nation protects a population of eastern pondmussels residing in their tribal waters within the delta of Lake St. Clair. [3]: 12
Like many Unionoid mussels, female eastern pondmussels display a lure to attract their fish hosts (see video, right).
