Baron Barracuda -  Sinister sea fish with a monocle on the live-action children's marionette adventure DIVER DAN/SYN/1960. Baron Barracuda and his stooge sidekick, Trigger Fish lived in the Sargasso Sea in a cave by Teetering Rock. They continually hatched plans to take over the bottom of the ocean. Their main adversaries were the only two humans on the program: intrepid ocean explorer Diver Dan (Frank Freda) and his mermaid friend Miss Minerva (Suzanne Turner).

Other fish marionettes (voiced by Allen Swift) included: Finley Haddock, Gabby the Clam, Gill-Espie, a bongo-playing beatnik fish, Glow Fish who lived by the Bottomless Pit, Goldie the Goldfish, Hammer-head Shark, Hermit Crab, Sawfish Sam, Scout Fish, who sported an Indian tomahawk and feathers, Sea Biscuit the Seahorse, and Skipper Kipper.

The Diver Dan program was produced by Hal Tunis and Louis Kellman and each episode ran seven-minutes in length.
