Mussels have gills and eat plankton.
A healthy female can lay more than 20,000,000 eggs and sometimes eat their their own young. A mussel can close itself from the outside world for between an hour to 6 hours. Most mussels can be eaten,but some are poisonous if they have fed on dinoflagellates. They are seldom eaten in the US,but are enjoyed in Europe. Salt water mussels are around 2 in.
