Word Origin & History

medusa 
"jellyfish," 1758, as genus name, from the name of one of the three Gorgons with snakes for hair, whose glance turned to stone him who looked upon it (attested in Eng. from 1390). Her name is from Gk. Medousa, lit. "guardian," fem. prp. of the verb medein "to protect, rule over" (see Medea). The zoological name was chosen by Linnæus, suggested by the creature's long tentacles.
