Etymology: "Phocoenid" is a scientific coinage, built on the Greek "phokaina", meaning "porpoise", which is itself related to "phoke", "seal". The ancient Greeks apparently linked porpoises with seals, a connection that modern biology has kept in a different form: porpoises are whales and dolphins, not seals at all. The Greek name passed into Latin and then into the Linnaean and later taxonomic vocabulary, where it became the genus "Phocoena" for the harbour porpoises. The ending "-id" is the standard zoological suffix marking membership of a family, so "phocoenid" means a member of the family Phocoenidae, the porpoises. Taxonomists formed these family names in the 19th century from the type genus, following the same pattern used for names such as "felid" and "canid". The word is therefore a technical coinage rather than a term used in everyday speech, and it dates from the period when modern zoological classification was taking shape.
