Mostly what I know of the Superman/Aquaman Adventures for the brief, almost single episode Teen Titans series, featuring the original Silver Age roster: Robin, Speedy, Wonder Girl, etc.
Actually, Robin WASN'T part of The Teen Titans in those days, nor was Batman a member of The Justice League of America. I think it had something to do with ABC-TV's live action Batman show.
The Dynamic Duo didn't even become part of that DC Filmation Universe until 1968, when ABC cancelled the show.
Does anyone have any idea why Aquaman was never in any of the JLA cartoons? He was featured in the promos, as shown in this link:
