Word Origin & Etymology

Borrowed from Latin Medusa, from Ancient Greek Μέδουσα (Médousa), literally meaning "guardian" or "protectress," derived from the verb μέδω (médō, "to protect, rule over"). The biological sense was coined by Carl Linnaeus in 1752 in allusion to the tentacled movement of the jellyfish resembling the mythological Gorgon's snake-like hair.
