  1. Lifestyles In Ocean Zones

  2. In The ZoneLifestyles Explanation: This Power Point is included in this presentation as a review of basic terminology and information.

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

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

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

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

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

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

  9. Ocean Zones(surface to ocean floor) Epipelagic Zone • Photic Zone or Sunlight Zone Mesopelagic Zone • Disphotic Zone or Twilight Zone Bathypelagic Zone • Aphotic zone or Midnight Zone Abyssopelagic Zone • Aphotic Zone or Midnight Zone Hadopelagic Zone • Aphotic Zone or Midnight Zone

  10. Epipelagic Zone 0 Mesopelagic Zone 200 Bathypelagic Zone Abyssopelagic Zone Hadopelagic Zone 1000 4000 6000 11,000

  11. Epipelagic Zone • Photic Zone • Enough sunlight for photosynthesis • Primary area of food production • From surface down to about 200 meters 0m Epipelagic Zone 200m Sunlight Zone Photic Zone

  12. Mesopelagic Zone • Dysphotic Zone • Not enough sunlight to support photosynthesis • From about 200 m down to 1,000 m Mesopelagic Zone 200m 1,000m

  13. Midnight Zones • No sunlight • From 1,000 m down to ocean floor, or around 11,000 m • Low density and diversity of marine life 1,000m Midnight Zone 11,000m

  14. Bathypelagic Zone • No sunlight • From 1,000 m down to 4,000 m • Low density and diversity of marine life 1,000m Bathypelagic Zone 4,000m

  15. Abyssopelagic Zone • No sunlight • From 4,000 m down to 6,000 m • Low density and diversity of marine life 4,000m Abyssopelagic Zone 6,000m

  16. Hadopelagic Zone • No sunlight • From 6,000 m down to ocean floor, or around 11,000 m • Low density and diversity of marine life 6,000m Hadopelagic Zone 11,000m

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

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

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

  20. Phytoplankton • Cyanobacteria • Diatoms • Coccolithophores • Dinoflagellates

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

  22. Zooplankton

  23. 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

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

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

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

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

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

  29. Nekton(swimmers) • Cartilaginous Fish • Sharks • Rays • Skates

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

  31. Benthos(bottom dwellers) • Live either on or attached to the bottom • Primarily filter feeders or scavengers

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

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

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