In Japan, the program debuted with the 1965 Dolphin Prince series, consisting of just three episodes in black and white. The first 13 color episodes aired in the second series, entitled Hang On! Marine Kid (Ganbare! Marin Kiddo) and broadcast from 1965 to 1966. Finally a third series - Undersea Boy Marine Kaitei Shônen Marin) - aired over two seasons with 36 episodes shown in 1969, and 78 episodes broadcast in 1971. It is the second season of this final series that was dubbed for broadcast in English, and the English-language versions were broadcast internationally significantly before their Japanese-language equivalents were first aired in the Japanese market. Broadcast information and records tend to indicate that in total, 130 episodes were produced, although this may simply be an indication of the number of episodes broadcast; the major problem with information about the series is that the main title was changed three times. What isn't known is whether episodes were simply lifted out of one series and re-imported into another for a 'repeat'.
