A mollusk is a soft bodied animal which protects itself with a shell. Bivalves have two shells which are connected with a small hinge. Oysters can open their shells to take in food as well as expel waste substances from their systems, and they can close their shells if threatened by predators. Like other mollusks, oysters have relatively simple biological systems, and they can be found in brackish water as well as salt water.
