DESCRIPTION
Mytilopsis sallei is a small, fingernail sized mussel, growing to an average size of 25mm, although sizes range from lengths of 8-25mm, with a maximum width of 9.68mm and a maximum height of 12.58mm. It has a varied shell colouration, from black through to a light colour, with some small individuals having a light and dark zig-zag pattern. The right valve overlaps the left valve, and is slightly larger. M. sallei settles in clusters, and is rarely seen as a single individual (NIMPIS, 2002).
 
NATIVE RANGE
World: Atlantic - Western Central, Guatemala, United States, West Indies
 
KNOWN INTRODUCED RANGE
ASEAN: Singapore
WORLD: Australia, Hongkong, Japan, Fiji, India, Mexico, Taiwan
 
PATHWAY
Transport – Ship/boat hull fouling
 
REASON FOR INTRODUCTION
Hull fouling is often an important factor in incursions, such as the introduction of M. sallei to Darwin Harbour, Australia in the 1990s (Hutchings et al. 2002).Spread via ballast water appears less likely because of the short duration of the larval stage (CSIRO, 2001).
 
IMPACTS
Mytilopsis sallei is an extremely prolific and fecund species, being ecologically similar to its relation the zebra mussel Dreissena polymorpha. It has been responsible for massive fouling on wharves and marinas, seawater systems (pumping stations, vessel ballast and cooling systems) and marine farms. In preferred habitats, it forms dense monospecific groups that exclude most other species, leading to a substantial reduction in biodiversity in infected areas (NIMPIS, 2002; CSIRO, 2001).
