Etymology
the term 'pupfish' is a modern english compound word, formed in the 20th century. it combines 'pup', referring to the small size and perhaps perceived playfulness of the animal, with the generic term 'fish'. this name was coined by biologists to describe these diminutive cyprinodonts, drawing on the familiar analogy of a puppy to convey their small stature within the fish world. the name is purely descriptive and has no deeper etymological lineage from classical languages, representing a straightforward taxonomic vernacular.
