Etymology: "Cyprinodonts" is the plural of "cyprinodont", and the singular is the older form of the two. Its parts come from Ancient Greek: "kuprinos" meant "carp", and "odon" meant "tooth". Put together, the name describes a fish with carp-like teeth, a label coined in scientific Greek-based naming rather than something handed down from antiquity. The Greek roots show up in many other scientific names. The "-odont" ending, from "odon", is a common building block for naming teeth in zoology, so a reader who has met words like "mastodon" (literally "breast-tooth") has already seen the same element at work. Here, the carp reference points to the group's close relationship with the true carps, a family of fish familiar to anglers and aquarists.
