Etymology: Darwinulidae is a taxonomic family name, and its history is a plain technical coinage rather than a story of common usage. It is built from "Darwinula," the name of the genus that gives the family its title, and the genus was named after Charles Darwin. The Latin-style "-idae" ending is the standard suffix that zoologists attach to a family name, drawn from the stem of the type genus. Darwinulidae therefore belongs to the same naming system as countless other animal families, where the root word is a genus and the ending marks rank. The genus name carries the more interesting link. Scientists honoured Darwin by building a diminutive form of his surname, and the "-ula" ending gives the sense of a small Darwin, a fitting tribute to a naturalist who spent years studying small and overlooked organisms such as barnacles and earthworms. The members of the family are ostracod crustaceans, tiny animals enclosed in a bivalve shell, and most live in freshwater.

Synonyms: ostracods, seed shrimp, crustaceans
