About the Data
Species records include data on invasions history, distribution, ecology, impact, and more. These data were gathered from published literature and targeted surveys. All records have undergone expert review, unless otherwise noted.
Species Profiles
NEMESIS includes detailed information on about 500 species of marine and estuarine of invertebrates and algae introduced to the United States. Each record contains information on taxonomy, distribution, ecology, and impacts, as well as references.
Rangia cuneata
Rangia cuneata is commonly known as the Gulf Wedge Clam, the Atlantic Rangia, and the Common Rangia. Its native range extends throughout the Gulf of Mexico from Campeche, Mexico to the southern tip of Florida. Introduced populations are established on the East coast of North America from North Carolina to the Hudson River, New York. There is some discussion about whether these represent a human mediated introduction or the resurgence of small, previously unnoticed relict populations. Introduced populations are also established in Belgium and the Baltic Sea. This species burrows in the muddy and sandy bottoms of estuaries, most commonly at salinities of 0-10 PSU, although salinities of 2.5-14 PSU are required for reproduction. In some locations, R. cuneata is a fouling nuisance in pipes and water intake systems.
