The Sea Devils were a group of adventurers published by DC Comics not unlike the Fantastic Four, which premiered right about the same time.  Both groups featured an intrepid scientiest, his blonde girlfriend, his burly buddy and a teenage member of the group.  The Sea Devils explored the oceans.  The Fantastic Four explored everywhere else.  And they had super-powers.

The "Sue Storm" of the Sea Devils was Judy Walton.  She usually didn't do much besides defer to Dane Dorrance, the "Reed Richards" of the group, and look nice in a wetsuit.  It the early 60s, that was progressive.
