A mussel is a bivalve, which means it has two shells that are hinged together to protect its soft body.
One has one and one has two
The limpet has only one shell, making it a univalve. Molluscs with two shells, such as clams and mussels, are bivalves.
An oyster - bi (stand for two) and valves (stands for shells) - two shelled animals.
Strictly speaking, no, though an organism cannot simultaneously be both.
Bivalves, univalves, and cephalopods are all types of mollusks. So are gastropods.
