seafood

This term serves as a collective category for any marine animal suitable for human consumption. It carries a culinary connotation, evoking images of menus, markets, and coastal dining rather than biological or ecological contexts. While it encompasses a wide variety of species, it is treated as a single food group.

Grammatically, this word is an uncountable mass noun. It cannot be pluralized to describe multiple types of fish or shellfish; instead, speakers must use partitive constructions such as "types of seafood" or "a variety of seafood" to specify different kinds of marine produce.
