Limnoperna fortunei (Dunker, 1857)

Diagnostic features

Limnoperna fortunei is very similar to Xenostrobus securis. Limnoperna is typically yellowish in colour (it is commonly known as the golden mussel), while Xenostrobus is typically brown to black. Also, young specimens of X. securis have zig-zag brown markings not seen in Limnoperna.  Xenostrobus securis has been referred to Limnoperna by several authors, however this relationship requires further investigation.

Biology and ecology

Limnoperna fortunei is a filter feeder found in brackish and fresh water. It can occur in great numbers, and populations can grow very rapidly. The preferred habitat of Limnoperna fortunei is on rocks and gravel, or any other hard surface, where it attaches to the substrate with a byssus.

Distribution

Native to China, but introduced into other parts of Asia as well as South America.

Notes

Limnoperna fortunei is an invasive brackish and freshwater species. There is often an associated decline in the presence of native freshwater bivalves in areas where it has invaded.

This species has so far not been recorded in Australia, however it is considered a potential risk as it has become highly invasive elsewhere.
