About mussels

Mussels are filter feeder bivalves, recognisable by an elongated shell which is often dark blue, blackish or brown, with a nacreous interior and the presence of a byssus (threads) that the mussel uses to attach itself to its environment.  There is a large variety of species that are found either in fresh or sea water, but the majority of the mussels are found in the temperate seawater areas at shallow depth from the intertidal areas to 50 metres. Mussels have been consumed by humans for thousands of years.  Their ease of access, preparation, and high protein content has made it a very popular dish across the world.
