Poor Knights Islands- New Zealand’s Volcanic Ocean Sanctuary - FD Ocean

#FreeDocumentaryNature #Documentary #Ocean
Off the coast of New Zealand’s Northland, the Poor Knights Islands rise from the Pacific as a protected world of volcanic cliffs, underwater arches and thriving reefs. In this marine reserve, stingrays gather in mysterious formations, gannets dive from the sky, reef fathers guard fragile eggs, and night hunters emerge after dark. But when a dominant male wrasse disappears, one female begins an extraordinary transformation - changing sex to take his place and keep the next generation alive.
