Dinoflagellates are a group of protists that can glow in the dark, a phenomenon known as bioluminescence. Some dinoflagellates also produce toxins that can cause harmful algal blooms, known as red tides, which can be toxic to marine life and humans when ingested.
Protists can be both helpful and harmful. Some protists are beneficial as they play key roles in ecosystems, such as being primary producers in marine environments. However, some protists can also be harmful pathogens that cause diseases in humans, animals, and plants.
