Nobody talks about this one. That needs to stop. Dolphin Prince exists in that impossible space where 1965 television actually tried something, a three-episode gamble on undersea adventure that moves with the confidence of a show that knows exactly what it is, even if the world forgot it existed the moment it ended. The black and white cinematography doesn't soften the strangeness; it amplifies it, turning what could have been disposable kiddie fare into something genuinely eerie and alien. Watch it for the mermaid mythology, stay because you're watching anime's earliest proof that someone was willing to build entire worlds just to see if they could make them stick.
A young boy with mysterious dolphin powers navigates the depths of the ocean alongside Neptuna, a mermaid who becomes his closest ally. Together with Dr. Mariner, a scientist studying the sea's hidden wonders, they face threats that emerge from the darkest trenches and most unexpected corners of the underwater realm. Strange phenomena plague the ocean: swirling vortexes that defy explanation, inexplicable calls echoing through the waves, and an invasion from an otherworldly species determined to claim dominion over the seas. What begins as simple exploration becomes a fight for survival as our heroes confront dangers both natural and extraterrestrial. The boy must learn to harness his unique abilities while trusting his companions to survive encounters that test their courage and loyalty. Between the scientific mystery and the unknown threat, questions mount about what truly lurks beneath the surface and whether humanity and the ocean's creatures can coexist peacefully. This 1965 series captures the adventurous spirit of early sci-fi television, blending action-packed sequences with genuine wonder at the ocean's infinite mysteries.
