Family THIARIDAE

Tarebia granifera (Lamarck, 1822) Introduced

A freshwater prosobranch originating from South-East Asia, Tarebia granifera can tolerate high salinities for relatively long periods of time and is therefore found within estuaries. It has spread rapidly across a number of countries in recent years, displacing other invertebrates. It was first recorded in St Lucia Estuary on the east coast in 2005 and by 2007 had spread along the eastern shores, as far as Kosi Bay ( Miranda 2009).
