Unveiling the Mysteries of Sea Life

The video explores the vast and varied marine environment, highlighting human familiarity with iconic species like whales and dolphins. It discusses the ocean's crucial role in climate regulation and the diversity of marine life, which is mostly found in sunlit upper layers. Coral reefs thrive in warm tropical waters, while polar regions support krill populations due to high oxygen levels. Despite our reliance on oceans, our understanding of their complex ecosystems is limited, and human activities pose significant threats. The deep ocean remains largely unexplored, with many species yet to be discovered.
