Oceanus

Oceanus was the titan of all of the water on Earth. Oceanos was depicted in ancient Greek vase paintings as a bull-horned god with the tail of a serpentine fish in place of legs, similar to his river-god sons. His usual attributes were a fish and serpent. He had a wife who was a nurse and it is thought to be that she had distributed his water through natural springs underground. Unlike his brothers he didn't take part in the war against the younger gods of Olympus.
