Jabberjaw was a Hanna-Barbera cartoon series created in 1976, starring a fictional shark named Jabberjaw and his four young adult cohorts, who had various adventures in a futuristic underwater world. The quintet also performed regularly as a rock group called the Neptunes.

The Neptunes consisted of:

• Jabberjaw: The Neptunes' drummer. Jabberjaw was a great white shark whose voice sounded similar to Curly of the Three Stooges series. Jabberjaw found it hard to get respect in a society where "shark ejectors" (robots that would guard various buildings or cities against sharks being allowed to enter) were commonplace, prompting him to frequently utter his catchphrase (borrowed from 1970s comedian Rodney Dangerfield): "No respect!"

• Biff: A brunette-haired young man, Biff was the band's guitar player and level-headed leader, similar to Scooby-Doo's Fred Jones.

• Bubbles: A blonde-haired young woman, Bubbles played piano for the Neptunes. She was extremely ditzy and dimwitted, similar to Josie and the Pussycats' Melody Valentine.

• Clamhead: Played bass guitar for the Neptunes. Clamhead tended to be either somewhat nervous or fairly impressed by new things (his catchphrase was "wowee-wow-wow!"). Clamhead was Jabberjaw's best friend, and bore a strong resemblance to Scooby-Doo's Shaggy.

• Shelly: A brunette-haired woman, Shelly played tambourine for the Neptunes. Shelly's personality was very abrasive, similar to Josie and the Pussycats' Alexandra Cabot), and she held a great deal of contempt for Jabberjaw (or "ol' blubberhead" as she'd call him).

Per a great deal of Hanna-Barbera's output in the 1970s, the format and writing for Jabberjaw was similar to that for Scooby-Doo or Josie and the Pussycats. The show also drew inspiration (in the use of a shark as a character) from the then-recent film Jaws. It also shared The Flintstones' penchant for making use of puns as the names of locations, people, etc., in this case, ocean-themed puns (such as "Aqualaska" instead of Alaska).

Thirteen episodes of Jabberjaw were produced. Jabberjaw himself later appeared on the series Yogi's Space Race and later still in sporadic appearances on Cartoon Network's Harvey Birdman.
