Dolphin Island / Iruka no shima (Paperback Bunko)

Arthur C. Clarke's portrayal of the dolphins felt so vivid and alive. I wonder if he drew from real dolphin behavior or created them entirely from imagination.

The way the island and its creatures were described made me nostalgic for childhood explorations. How did the author manage to evoke such a pure sense of discovery?

Given current environmental concerns, I’m curious whether readers see this story as timeless or as a reflection of its era. Did it inspire anyone to think differently about wildlife?
