The Skeletons are the secondary and final antagonists of Ray Harryhausen's Jason and the Argonauts. They are an army of Skeletons bred from the Hydra's teeth used by King Aeëtes of Colchis. They fought Jason and two other Argonauts, Phalerus and Castor, after stealing the Golden Fleece of Colchis. In the fight, Phalerus and Castor were both killed and Jason jumped off a cliff into the sea, escaping the Skeletons who chasing after him, fell into the sea, presumably killing them all.
