Taxonomic Group: Mollusks-Gastropods


Pleurocera canaliculata is a small freshwater snail commonly known as the Channeled Hornsnail. Recent genetic analysis shows that snails described as P. acuta and P. pyrenellum are phenotypic variants of this species. It has a broad native range in North America, spanning from Minnesota and Quebec to Alabama and Louisiana. It was introduced (as the P. acuta morph) to the tidal reaches of the Hudson River, New York. It may have been transported through the Erie Canal on barges. It is known from a variety of habitats, including lakes, ponds and rivers and is found on mud, sand and rock substrates. No impacts have been reported for this species.
