  2. Ocean Zones(shoreline to open ocean) • Intertidal Zone • Neritic Zone • Oceanic Zone • Benthic Zone

  3. Intertidal Zone Neritic Zone Oceanic Zone Sunlight Continental Shelf Benthic Zone

  4. Intertidal Zone • Area between high tide line and low tide line • Organisms adapted to harsh, changing environments Intertidal Zone Continental Shelf

  5. Neritic Zone • Area over the continental shelf • Area of greatest density and diversity of marine life Neritic Zone Continental Shelf

  6. Oceanic Zone • From the continental break out to open ocean Oceanic Zone Continental Shelf

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

  8. Lifestyles • 3 Basic Lifestyles: • Plankton • Nekton • Benthos

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

  10. Plankton • Meroplankton • Spend only part of their life cycles as plankton • Are the larval stages of organisms that grow to become benthic or nektonic organisms • Holoplankton • Spend their entire life cycles as plankton

  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. Phytoplankton • Cyanobacteria • Diatoms • Coccolithophores • Dinoflagellates

  13. Zooplankton • Foraminifers • Radiolarians • Cnidarians • Combjellies • Arthropods • Larvae

  14. Zooplankton

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

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

  17. Nekton(swimmers) • Marine Reptiles: • Turtles • Snakes • Crocodiles • Iguanas

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

  19. Nekton(swimmers) • Bony Fish: • Tuna • Barracuda • Eels • Angler Fish

  20. Nekton(swimmers) • Cartilaginous Fish • Sharks • Rays • Skates • Chimeras

  21. Nekton(swimmers) • Marine Arthropods • Shrimp • Mollusks • Squid • Octopi

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

  23. Benthos(bottom dwellers) • 2 Basic Types: • Sessile - Live attached to the bottom • Vagrant - Able to move about

  24. Benthos(bottom dwellers) • Sessile: • Barnacles • Sponges • Corals • Sea Anemones • Oysters • Clams

  25. Benthos(bottom dwellers) • Vagrant: • Crabs • Sea Stars • Sea Cucumbers • Sea Urchins • Brittle Stars
