DinoflagellatesDivision: DinophytaDinoflagellates

Division: Dinophyta

• Two distinct flagella

• Photosynthetic

• Cause of harmful algal blooms• The sudden multiplication of dinoflagellates• Commonly called Red Tide

RED TIDESRED TIDES• Sudden, rapid growth of dinoflagellates

• Poisons and kills fish- very harmful to the fishing industry.

• Accumulate in shellfish

• Toxins can be fatal: Symptoms may begin with tingling in the limbs, then paralysis of the diaphragm which leads to suffocation.

• Other symptoms may include amnesia, muscular paralysis, hallucinations, diarrhea, or abdominal cramps.

• Giant kelp forests are brown algae

• Usually reach about 100 feet

• Largest: 900 feet

• Can regenerate their blades

Red SnowRed Snow

• Caused by an algae called Chlamydomonas nivalis

• It is a green algae with a secondary carotenoid pigment that protects the chloroplast from UV radiation

Ice CreamIce Cream

• A gum extracted from the algae called carrageenan is put in most ice creams

• The algae loves water- it ties up the water in the ice cream making it thick and smooth instead of thin and runny

• Only a half-teaspoon is used in a half gallon of ice cream
