Musculista senhousia
Taxonomic Group: Mollusks-Bivalves


Musculista senhousia is commonly known as the Senhouse Mussel. It is native from the southern Kurile Islands, Russia to Japan and Singapore. It is also established in the Indian Ocean, but its status (i.e. native or non-native) in this region is unknown. It is introduced in the northwest Pacific (from Mexico to British Columbia), the southwest Pacific (Australia, New Zealand), the northeast Atlantic (Mediterranean and Atlantic France), and the tropical west Atlantic (Venezuela). This mussel can settle on soft and hard substrates. In soft habitats, such as mudflats, it creates mats of byssal threads. In some instances, native suspension feeders have declined or disappeared in the presence of M. senhousia.
