1. Marine Microbes

2. Marine viruses are best controlled by enzymes secreted by their hosts.
Commonly found in marine environments.
10X more abundant than marine prokaryokes.
Bacteriophages are viruses that attack marine bacteria.
Bacteriophage
Marine viruses are best controlled by enzymes secreted by their hosts.

3. The Lytic Cycle
Describes the process, within a host of viral replication – not recognized as a method of reproduction.
Bottlenose dolphin infected with herpes.

4. Eubacteria Autotrphic & Heterotrophic
Found in all waters regardless of abiotic factors.

5. Cyanobacteria: Stromatolites

6. Chemosynthetic Bacteria
Decompose large molecules (sulfur) rather that photosynthesize.
Found in locations where sunlight is not available.
Produce carbohydrates to “feed” deep sea food webs.
                                                              

7. Archaea AKA: Extremophiles
These ancient microbes are a link between prokaryotes and eukaryotes.
They thrive in conditions where other organisms suffer.
Hyperthermophiles
Methanogens
Halophiles

8. Eukaryotes

9. Marine Fungi Less than 1% of all fungi are marine.
Most do not form spores but spread via hyphae or by budding.
Maritime lichens (fungi + algae) are common on rocky shores.

10. Diatoms Important pyhtoplankton key to pelagic marine food webs.
Have glassy (silica) shells called frustrules that fit together like a shoebox.
Locomotion by
cillia of secretion
of mucus.

11. Dinoflagellates Autotrophic AND Heterotrophic
Produce Harmful Algae Blooms (HABs)

12. Amoeboid Protozoans
Formaniniferans have shells made of calcium and create calcarious ooze that leads to the formation of limestone (chalk).
