In our waters, there are some species of phytoplankton (tiny algae) that produce powerful toxins. When surrounding conditions become good for them, they multiply very fast, or ‘bloom’. The toxins build up in clams, crabs, and other shellfish as they eat these plankton. Eating toxic shellfish can make you very sick or even kill you.
