Alexandrium fundyense

Alexandrium fundyense is a type of microscopic plankton, specifically a dinoflagellate, found in cold coastal waters. It can produce toxins that accumulate in shellfish like clams and mussels, leading to poisoning in humans who consume them. When conditions like warm temperatures and nutrient-rich waters favor its growth, it can form large blooms, known as red tides, which discolor the water. These blooms can be harmful to marine life and pose health risks to people, making monitoring and managing their presence important for seafood safety and environmental health.
