Scolopendra

Historical Background
Also spelled Skolopendra, in Greek mythology, it was a gigantic sea monster depicted as having rows of webbed feet along its flanks, a flat, crayfish-styled tail, and hairy nostrils. It was considered the largest type of sea monster (Ketos). Given the reports of nostrils, something only found with oxygen-breathing creatures, this may be a very crude early report of some kind of whale. Its name means "millipede" in Greek.
