Etymology: Lamnidae is a scientific family name, coined in the 19th century rather than in antiquity. It is built on "Lamna," the genus name given to the porbeagle shark, and the family suffix "-idae," which zoologists attach to family names across the animal kingdom. The genus "Lamna" was itself created by the naturalist Constantine Samuel Rafinesque in 1810, drawing on the Greek "lamia," a word for a monstrous sea creature with a ravenous appetite, which in turn is tied to a figure of Greek myth who devoured children. The family was named later in the nineteenth century, when classifiers grouped the porbeagle with its close relatives, the mako and great white sharks, into a single lineage. Its name therefore records an old mythic image of a voracious monster, rather than anything the fish were called by ancient observers.

Synonyms: mackerel sharks, great white sharks, shortfin mako, longfin mako, porbeagle
