The team was introduced in Showcase #27 (July-August 1960) - #29 (November-December 1960). They then got their own title which lasted 35 issues (1961–67).
The team consisted of leader Dane Dorrance, Biff Bailey, Judy Walton (Dane's girlfriend), and Nicky Walton (Judy's younger brother). During a one issue crossover story with the Challengers of the Unknown in Challengers of the Unknown #51, they fight the criminal group known as Scorpio. The team also has affiliated allies called the International Sea Devils: Molo from Africa, Sikki from India, and Miguel from South America. They also sometimes team up with a magically cursed, green skinned amphibian man they called the Man-Fish (Juan Vallambrosa) and a group of diving students called the "Tadpoles".
More than ten years after the cancellation of their title, the team takes a small part in the defeat of an alien invasion in Showcase #100 (May 1978). Then, Dane and Judy (now married) help out Christopher Chance, the Human Target in Detective Comics #486 (October-November 1979).
The Sea Devils (usually only Dane) later appear as part of the Forgotten Heroes team.
They help in another alien invasion, this time by the Apellaxians. They assist in entrapping a group of 'Mercury' aliens, assisted by Aquaman and Cave Carson. This is set chronologically early in their career.
