Gadidae

This term is a technical taxonomic designation used primarily in ichthyology and marine biology. It refers to the family of cod-like fishes, encompassing species such as cod, haddock, and pollock. Because it is a formal Latinate family name, it is typically used in scientific literature or academic contexts rather than in casual conversation.

In biological nomenclature, family names ending in -idae are treated as collective nouns referring to the group as a whole. While the members of the family are countable individuals, the term "gadidae" itself functions as a singular taxonomic category.
