Etymology: "Mesoplodont" is the singular form of the word, and "mesoplodonts" is its plural, used for the whales of the genus Mesoplodon. The name is built from Greek roots: "mesos" meaning "middle" and "odous" meaning "tooth," with "-plo-" linked to the Greek word for "double" or "folded" and "-don" meaning "tooth" again. Together they describe a whale with teeth in an unusual position, since the teeth of many species in the group sit in the middle of the lower jaw rather than at the front or sides. The genus name was coined by scientists using Greek building blocks, which is typical of the Latinized and Hellenized naming used for animals in the 19th century. The ancient Greeks had no word for these whales, so the term is a modern scientific creation rather than a traditional one.
