Etymology: Mesoplodon is a genus of beaked whales, and its name was coined in 1816 by the French naturalist Henri Marie Ducrotay de Blainville, who built it from Greek roots. "Mesos" means "middle" and "hoplon" means "weapon" or "tool," while "odous" (genitive "odontos") means "tooth." The name refers to the pair of teeth that grow from the lower jaw of the males, which are placed in the middle of the jaw rather than at the tip or the back, a feature that distinguishes the genus. Early scientists found these teeth so unusual that they shaped the naming around them. The "middle" in the name points to the teeth's position, and the "weapon" points to the fact that they seem to serve as a display or fighting feature in males. The word is a fully modern scientific coinage from classical elements, so no ancient Greek writer ever used it or knew the animals it describes.
