| Unlike a free alga, the symbiotic dinoflagellate is not directly in contact with seawater, since it is intra-cellular, inside the endodermic cells of the animal, inside a vesicle. |
| Our laboratory works with the dinoflagellate Gonyaulax polyedra, a unicellular marine protist. |
| The relative abundance of each poison varies with the species and strain of dinoflagellate. |
| Each dinoflagellate has two flagella, chloroplasts and Cellulose plates covering their body. |
| On the west coast of North America, clams and mussels become poisonous by ingesting the dinoflagellate Gonyaulax catenella and accumulating saxitoxin in the digestive tract. |
| The rise and fall of toxic algae A. tamarense is a unicellular dinoflagellate that naturally occurs in the St. Lawrence ecosystem. |
