Ostreopsis Blooms and Marine Ecosystems

The video discusses the vast coverage of oceans and the diversity of marine life, focusing on microscopic organisms like microalgae. It highlights the role of microalgae in marine ecosystems and the impact of bentic dinoflagellates, which can produce toxins. The video also explores the dynamics of ostreopsis blooms, their health and environmental impacts, and ongoing research to understand and mitigate these effects.
