Kareniaceae

Kareniaceae is an accepted marine family of relatively small, toxic, unarmored dinoflagellates belonging to the order Gymnodiniales.^[1][2] Species in the Kareniaceae clade often cause harmful discolored green algal blooms (HABs) that pose a safety and health risk to humans (H. sapiens) and the surrounding regions. Such blooms also pose a risk to coastal aquaculture worldwide, especially in places like France, the Atlantic Ocean, the English Channel and the Mediterranean Sea.^[3][4]
