2. In The Zone Lifestyles 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 Continental Shelf

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

Shelf

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

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

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 Holoplankton
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 Manoeuver 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
Octopus

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
