Ecological Significance
- Major role at the base of the food chain
- Cause red tide- Harmful Algal Blooms (HAB)
Harmful Algal Bloom
-When colonies of algae grow out of control
-Can be harmful: some species release toxins
- kill fish; shellfish dangerous to eat; humans breathe in toxins
-Harmful effect on marine systems:
- masses of algae die
- decompose and deplete O2
- fish either leave or die
The Fire Algae
ex: Dinoflagellates
- Mostly unicellular flagellates
- Eukaryotic
- Chloroplasts, if present, are golden brown to yellowish green.
- Motile cells with two flagella
- Cell walls of cellulose
- Valves (shells) made up of interlocking plates
- Eyespot to seek out light
- Feeding: Most are photosynthetic autotrophs
- Some are saprophytes
- Some are parasitic
- Some are endosymbionts
- Habitat: mostly warm oceans
- can be found living in plankton, coral, sand
- as parasites in marine life
BIOLUMINESCENCE!
- Reproduction is mostly asexual but rarely sexual reproduction will occur
