What organisms are most often involved in red tides?

Answer 1

The most common organisms involved in red tides, specifically harmful algal blooms (HABs), are certain species of dinoflagellates. These microscopic algae include genera such as Karenia, Alexandrium, and Pyrodinium. These dinoflagellates are known to cause red tides and produce harmful toxins that can have detrimental effects on marine ecosystems and human health.
