Enalus

Enalus was a young man who was rescued by a dolphin (like Arion) when he leaped overboard from a ship to join his love Phineïs. (She had been thrown into the sea to appease Amphitrite, and was herself also rescued by a dolphin - the mate of the one that rescued Enalus.)

His name means 'one of the sea' - perhaps we should call him 'Young Man of the Sea' to counterbalance all those Old Men of the Sea - from enalion, 'of the sea' (en, 'in' and hals, 'sea').
