Freshwater shrimp (Palaemonetes Australis) may be involved in glochidia release from the freshwater mussel(Westraluno Carteri)

摘要

On 27 November 2010 while snorkeling in Canebreak Pool, Margaret River I observed interesting interactions between freshwater shrimp (Palaemonetes australis) and freshwater mussels (Westralunio carteri). First, it is necessary to give a brief explanation of the life cycle of the Unionoidea, a superfamily within the order Unionoida, which are characterised by their larval type (Parodiz and Bonetto 1963).
