This sp This species can quickly form dense colonies in a range of environmental conditions. Because of its dispersed spawning nature, lack of local predators, fast growth, and high tolerance of environmental conditions, this mussel population is expected to expand in Atlantic habitats until it reaches its thermal limits DeVictor and Knott, undated as stated in ISSG,
Found in numerous locations in Florida, the Asian green mussel has become an invasive species. An invasive species is those plants and animals that are not native to an area and which have a negative impact on native species, the environment, or human health. Invasive species can also have negative economic impacts due to their interactions with economically important species.

Perna viridisknown as the Asian green musselis an economically important mussela bivalve belonging to the family Mytilidae. It is harvested for food but is also known to harbor toxins and cause damage to submerged structures such as drainage pipes. Its shell ends in a downward-pointing beak.
Features : Juvenile is bright green, older shells are dark green to brown. Smooth with evenly spaced grooves. Grows 8—16cm long.

The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected.
The Asian green mussel is a large bivalve attaining a size up to 16cm in length. Juveniles are typically bright green in colour, with the adults turning dark green to brown. It is fast growing, can tolerate a wide range of water salinities and temperatures, and can be found in water depths of up to 42m. This mussel is capable of attaching to a variety of hard surfaces including vessels, buoys and aquaculture equipment often forming dense clumps.
Dense colonies can develop in optimal temperature and salinity conditions, sometimes with thousands of individuals per square metre. Perna species appear to thrive in intake pipes of industrial plants, where they may interfere with operation. It is susceptible to overgrowth from other fouling organisms that make it difficult to detect despite its vivid green appearance.
