Researchers at Yokohama National University have discovered a tiny marine fungus, Algophthora mediterranea, that can infect and kill harmful algae responsible for toxic blooms. The fungus targets species like Ostreopsis cf. ovata, which produce toxins affecting human skin, eyes, and lungs, and can also survive on pollen and multiple algae species. The discovery suggests that parasitic marine fungi may play a larger role in regulating ocean ecosystems than previously recognized. Scientists hope this insight could help predict and manage harmful algal blooms in the future.
