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

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

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

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

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

    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
