What was the Golden Age for Aquaman?
In his early Golden Age appearances, Aquaman can breathe underwater and control fish and other underwater life for up to a minute.
What other things can Aquaman do besides breathe underwater and control fish and other underwater life for up to a minute?
Initially, Aquaman was depicted as speaking to sea creatures in their own language rather than telepathically, and only when they were close enough to hear him.

Question: Did that change?
Self-contained rewrite: Did Aquaman initially being depicted as speaking to sea creatures in their own language and only when they were close enough to hear him change?
