Is there a scientific name for shellfish not the fish but the family?

Answer 1

There is no specific scientific name for shellfish because shellfish is a non-scientific way of describing a large number of invertibrate food items such as lobster, scallops, muscles and shrimp. Mostly 'shellfish' are either molluscs or crustaceans.

Answer 2

Yes, the scientific name for shellfish is Mollusca. Mollusca is a phylum that includes various species such as clams, oysters, mussels, and scallops, which are commonly referred to as shellfish due to their hard protective outer shells.
