Varuna litterata The River Swimming Crab
During recent aquatic biological studies of the Coffs Harbour City Council’s Local Government Area (CHCCLGA) we discovered the River Swimming Crab Varuna litterata. They are a marine crab known to occur in freshwater, being excellent swimmers and able to move with the currents along the coast. In Australia they have only been recorded from south east Queensland and north into Northern Australia (Qld Museum). They are also known to occur in India, East Africa and Japan. The discovery of this species this far south greatly increases the known distribution of the species in Australia and is a significant finding.
Devi et al (2013) from India found that they were estuarine crabs that are euryhaline (capable of tolerating a wide range of salt water concentrations) and are found to be distributed in areas with a more tidal influx.(You need to be a member to read the rest of this article.
