Where are Geukensia Demissa found?
Geukensia demissa, commonly known as the Atlantic Ribbed Mussel, ranges naturally from the southern Gulf of St. Lawrence to Palm Beach, Florida. It was first collected on the West Coast of North America in San Francisco Bay, California in 1894, where it was introduced with Eastern Oyster imports.
What do Geukensia Demissa eat?
Geukensia demissa feeds by filtering very small planktonic organisms and organic particles from the water. Researchers have found that it can affect the cycling of nutrients in Atlantic salt marshes, removing a third of the particulate phosphorus from suspension and depositing it on the mud surface (Kuenzler 1961).
Are ribbed mussels edible?
Although ribbed mussels are edible, they are tough and do not taste as good as the popular blue mussel. During low tide, ribbed mussels close their shells, keeping in waste products that can be toxic to humans.
How long do ribbed mussels live?
10 – 15 years
The ribbed shells of this species usually attain a length of 10 cm length, and can be as large as 13 cm. Age can be determined by counting dark growth rings on the shell and mussels typically live 10 – 15 years, but more advanced ages are not uncommon.
What do mussels eat in the wild?
Most mussels live around 60 to 70 years in good habitat. FEEDING: Mussels feed by filtering algae, bacteria, phytoplankton and other small particles out of the water column.
What do ribbed mussels eat?
Ribbed mussels constantly suck in and expel water as they consume plankton and plant particles through their gills.
Are brown mussels edible?

Why are ribbed mussels important?
Ribbed mussels play an important role in Rhode Island salt marshes as filter feeders, removing bacteria, heavy metals, and toxins from the water column. Unlike their relative the blue mussel, ribbed mussels are rich in organic bacteria and are not commonly eaten by people.
What do Atlantic ribbed mussel eat?
They literally find food by opening up their mouth and taking in whatever minute organisms happen to be swimming in the water at that time, and then filtering out all the unfavorable stuff. During high tide, ribbed mussels open their shells slightly to draw in water, filtering out algae and other particles.
What eats ribbed mussel?
Ribbed mussels, however, are extremely resilient. They can endure drought and extreme fluctuations in temperature and salinity. They are “photosensitive,” which means they can detect the presence of predators such as blue crabs or raccoons and quickly close their shells.
What do ribbed mussels need to survive?
The mussel is eurythermal, which means they can survive in extreme water temperatures from -7.6 to 104 degrees F. They can also survive in salinities from 5 to 100 parts per thousand.
Do mussels lay eggs?
Freshwater mussels have an unusual and complex mode of reproduction, which includes a brief, obligatory stage as a parasite on a fish. During the breeding season, females lay eggs and brood them inside specialized chambers in their gills called a marsupia.
