DinoflagellatesChrysophyta (still)

Photosynthetic, another major primary producer

Unicellular, have two flagella for movement, made of cellulose plates, may have spines, wings or horns.

Blooms can change the color of the water and even some can be luminescent.

Red tidesPytchodiscus

Occurs along the East Coast and Gulf Coast of the U.S. Create a toxin that causes high mortality of fish and other

marine vertebrates. Toxins interfere with nerve function and can result in paralysis.

Paralytic Shellfish poisoning caused by eating shellfish that have ingested Saxodomus

Zooxanthellae (type of dinoflagellate)

Symbiotic dinoflagellate associated with corals, giant clams, anemones, sea urchins, and some flatworms.

Zooxanthellae produce food for the organisms and without them the organisms cannot survive.

Marine Viruses

Viruses are considered non-living by many scientists.

They are the most abundant biological agent in the oceans There are 10 billion particles per liter of surface water.

Viruses effect phytoplankton’s production, and can even limit growth, divert phytoplankton blooms, and eventually effect

zooplankton and marine food web production.

Plankton Chronicles

http://www.planktonportal.org/http://www.planktonchronicles.org/en

http://www.origami-instructions.com/origami-for-kids.html

Step one: choose a phytoplankton Step two: Use plankton portal and Plankton Chronicles to find information about your

organism. Step three: Research your organisms name, location, relative abundance, phylum and

class, facts about your organism and what it looks like. Step four: create a 3D construct of your phytoplankton out of paper. Use origami tricks to

create a box or circle to begin with.
