GEOLOGY OF THE WORLD’S OCEANS

Survey of Marine Life1

Page 2: Survey of Marine Life1 - Utah State UniversityPhaeophyta (Brown Algae) Chlorophyta (Green Algae) Halimeda Chlorophyta Calcareous (Green Algae) Rapidly-growing green alga that indicates

Domain Bacteria

(Monera)

• Procaryotic

• Unicellular

• Photosynthetic or

Heterotrophic

• Planktonic or benthic

Base of many marine food chains

Kingdom Protista

• Eucaryotic

• Unicellular (t iny)

• Planktonic or Benthic

• Photosynthetic

Diatoms

Coccoliths

Dinoflagellates

• Heterotrophic

Forams

Radiolarians

Diatoms

• Siliceous

• Photosynthetic

• Planktonic or Benthic

• Base of many marine

food chains

• Main component of many

deep-sea siliceous oozes

Coccoliths

Form chalks – Kansas and

England, France

• Calcareous

• Photosynthetic

• Planktonic

Page 6: Survey of Marine Life1 - Utah State UniversityPhaeophyta (Brown Algae) Chlorophyta (Green Algae) Halimeda Chlorophyta Calcareous (Green Algae) Rapidly-growing green alga that indicates

Dinoflagellates

Responsible for

red t ide and

phosphorescence.

Some are symbiotic

w ith corals.

• Organic Walled

• Photosynthetic

• Planktonic or

Endosymbiotic

!Life saving t ip

#7 avoid seafood

during a red t ide

Forams

• Calcareous

• Heterotrophic

• Planktonic and Benthic

• Amoeba-like

Main component of many

deep-sea calcareous oozes
