Introduction

  • Alexandrium fundyense is a dinoflagellate
  • It has two flagella (one like a belt surrounding the cell body, the other along the body)
  • It has a theca, the "house" in which the cell body dwell, which is fit together by cellulosic plates like puzzle pieces
  • It lives in the upper layer of the ocean, and has weak mobility, hence it is called plankton
  • It is photosynthetic, hence a phytoplankton
  • It is widely distributed
  • It can cause harmful algal blooms (commonly known as "Red tides") as a result of active reproduction and low grazing by herbivores
  • It is capable of producing saxitoxin, a neuromuscular toxin that causes Paralytic Shellfish Poisoning (PSP); the toxin can be accumulated through the food chain and end up in shellfish and some filter-feeding fish, constituting health threat for animals and humans
