Caeneus was born a girl, Caenis (), the daughter of Elatus, but after Poseidon had sex with Caenis, she was transformed by him into an invulnerable man. Caeneus participated in the Centauromachy, where he met his demise at the hands of the Centaurs by being pounded into the ground while still alive.
