4. The Impact of the Intertidal Zone

5. Neritic Zone Area over the continental shelf

6. Open Ocean Zone From the continental break out to open ocean
Shelf

7. Benthic Zone The Ocean Floor Underlies all the other zones

8. Lifestyles
3 Basic Lifestyles:
Plankton
Nekton
Benthos

9. Ocean Lifestyles

10. Plankton Floaters or very poor swimmers
Plankton divided into 2 groups:
Phytoplankton – producers, photosynthesizers
Zooplankton – consumers

11. Phytoplankton Must live in the photic zone
Most abundant in shallow coastal areas or in upwelling zones
The basis of the oceanic food web

12. Zooplankton Foraminifers Radiolarians Cnidarians Combjellies
Arthropods
Larvae

13. Zooplankton

14. Nekton (swimmers) Free swimmers Maneuver actively in the water column
Found in the water column from surface to ocean floor

15. Nekton (swimmers) 5 Categories: Reptiles Mammals Fish Arthropods
Mollusks

16. Nekton (swimmers)
Marine Reptiles:

17. Nekton (swimmers) Marine Mammals: Whales Seals Otters Manatees
Dolphins

18. Nekton (swimmers)
Bony Fish:

19. Nekton (swimmers)
Cartilaginous Fish
Sharks
Rays

Chimaeras

20. Nekton (swimmers)
Marine Arthropods
Shrimp
Mollusks
Squid
Octopi

21. Benthos (bottom dwellers)
Live either burrowed in, resting on, or attached to the bottom
Primarily filter feeders, scavengers or deposit feeders

22. Benthos (bottom dwellers)
