Perna viridis, known as the Asian green mussel, is an economically important mussel, a bivalve belonging to the family Mytilidae, or the "true mussels". It is harvested for food but is also known to harbor toxins ^{[citation needed]} and cause damage to submerged structures such as drainage pipes. It is native in the Asia-Pacific region but has been introduced in the Caribbean, and in the waters around Japan, North America, and South America.^[2]
