Lifestyles
  • 3 Basic Lifestyles:
    • Plankton
    • Nekton
    • Benthos
plankton
Plankton
  • Floaters or very poor swimmers
  • Plankton divided into 2 groups:
    • Phytoplankton – producers, photosynthesizers
    • Zooplankton – consumers
phytoplankton
Phytoplankton
  • Must live in the photic zone
  • Most abundant in shallow coastal areas or in upwelling zones
  • The basis of the oceanic food web
phytoplankton20
Phytoplankton
  • Cyanobacteria
  • Diatoms
  • Coccolithophores
  • Dinoflagellates
zooplankton
Zooplankton
  • Foraminifers
  • Radiolarians
  • Cnidarians
  • Combjellies
  • Arthropods
  • Larvae
plankton23
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
nekton swimmers
Nekton(swimmers)
  • Free swimmers
  • Maneuver actively in the water column
  • Found in the water column from surface to ocean floor
nekton swimmers25
Nekton(swimmers)
  • 5 Categories:
    • Reptiles
    • Mammals
    • Fish
    • Arthropods
    • Mollusks

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

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