Karenia brevis

Karenia brevis is a marine single-celled algae found in the Gulf of Mexico, commonly known as red tide. When they rapidly multiply, they produce toxins that can discolor the water and harm marine life, birds, and humans. These toxins can cause respiratory issues, eye irritation, and skin reactions in people exposed, especially through inhalation or contact. Red tide events can also lead to fish kills and impact local economies reliant on tourism and fishing. Monitoring and managing these blooms are important to protect environmental health and public safety.
