Potamopyrgus acus is a critically endangered〔 species of fresh water snail native to New Zealand. == Habitat == This snail has been found in only one location in a gully, on a very small and steep limestone bank, at Limestone Downs Station in the Waikato. This snail was first discovered in 1981 but several surveys in 2002 and 2003 has failed to find any further specimens. The area has been cleared for agriculture and is under threat of damage by cattle. It is possible that this snail is extinct.
