means A member of a legendary crew sailing in quest of something rare and dangerous — originally the Golden Fleece, later borrowed for 1849 gold-seekers and even deep-sea octopuses.

from From Greek Argonautes, built from Argo, the ship Jason sailed, plus nautes, 'sailor.' The Argo itself was named for its builder, Argus, and the crew who rowed her into myth simply became 'Argo's sailors.' The word later resurfaced far from mythology: American prospectors chasing California gold in 1849 were nicknamed Argonauts for their own perilous voyage toward treasure, and naturalists later gave the name to a species of paper nautilus whose females drift the open sea in a delicate shell, as if still questing.
