Oysters obtain their food by pumping water through their system and filtering small organisms from the water they are almost constantly drawing over their gills.
They live mainly in temperate or warm coastal waters and grow near the bottom & attach themselves in clusters to hard surfaces called beds or reefs.
Oyster shells vary widely in form depending on what they attach to.
They change their gender once or more during their lifetime.
Oysters are a vital part of the ecosystem and work as a natural filter. Studies have found that an individual oyster filters about 30 to 50 gallons of water a day.
They filter pollutants out of the water and provide habitats for other species, such as barnacles and mussels.
Oysters are low fat, high protein seafood choice which are rich in calcium, magnesium & iron.
Their flavourful meat is considered as a delicious food all around the world and has a lot to offer in terms of health benefits.
