In Ocean Zones Lifestyles
In The Zone Lifestyles Explanation: This Power Point is included in this presentation as a review of basic terminology and information.
Ocean Zones (shoreline to open ocean) Intertidal Zone n Neritic Zone n Oceanic Zone n Benthic Zone n
Intertidal Neritic Zone Continental Shelf Oceanic Zone Sunlight Benthic Zone
Intertidal Zone n Intertidal Zone Continental Shelf n Area between high tide line and low tide line Organisms adapted to harsh, changing environments
Neritic Zone Area over the continental shelf n Area of greatest density and diversity of marine life n Neritic Zone Continental Shelf
Oceanic Zone n Continental Shelf From the continental break out to open ocean
Benthic Zone The Ocean Floor n Underlies all the other zones n Benthic Zone
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
Epipelagic Zone Mesopelagic Zone Bathypelagic Zone Abyssopelagic Zone 0 200 1000 4000 6000 Hadopelagic Zone 11, 000
Epipelagic Zone n n Epipelagic Zone Sunlight Zone 0 m 200 m Photic Zone n n Photic Zone Enough sunlight for photosynthesis Primary area of food production From surface down to about 200 meters
Epipelagic Organisms n n n Humpback whale Hammerhead Shark Leatherback Turtle n Tuna n Mola n Sea Otter
Epi- Adaptations n n Streamlined shape Countershading Blowhole on top Swim bladder- change buoyancy
Mesopelagic Zone n n Mesopelagic Zone 200 m 1, 000 m n Dysphotic Zone Not enough sunlight to support photosynthesis From about 200 m down to 1, 000 m
Mesopelagic Organisms n Swordfish n Opah n Cuttlefish n Orange Roughy n Lantern fish n Vampire Squid
Midnight Zones n n 1, 000 m Midnight Zone n 11, 000 m No sunlight From 1, 000 m down to ocean floor, or around 11, 000 m Low density and diversity of marine life
Bathypelagic Zone n n Bathypelagic Zone 1, 000 m 4, 000 m n No sunlight From 1, 000 m down to 4, 000 m Low density and diversity of marine life
Mid level Adaptations n Depend on other senses beside vision Lateral line n Bioluminescence n n Large eyes Echolocation Transparent bodies or black/red bodies
Functions of Bioluminescence n n n Headlight (lantern fish) Social interaction Lures to attract prey (angler fish) Counter-illumination (dappling confuses) Bright flashes and blobs ejected confuse predators/prey- act as decoys “burglar alarm”; illuminate predator so larger predator will be drawn to it
Bathypelagic Organisms n Basket Star n Gulper eel n Viper fish n Yeti Crab n Colossal Squid n Dumbo Octopus n Pacific Blackdragon n Patagonian Toothfish
Abyssopelagic Zone No sunlight n From 4, 000 m down to 7, 000 m n Low density and diversity of marine life n Abyssopelagic Zone 4, 000 m 6, 000 m
Abyssopelagic Organisms n Fangtooth Fish n Tripod Fish n Sea Pig
Deep Sea Adaptations n n n Bioluminescence- lures, detect prey Capable of going a long time w/o eating Large mouth with expandable jaw and stomach to feast Teeth point in- no escape! Don’t HUNT- too much energy Antifreeze in blood to keep it flowing!
Hadalpelagic Zone n n n Hadopelagic Zone 6, 000 m 11, 000 m No sunlight From 6, 000 m down to ocean floor, or around 11, 000 m Low density and diversity of marine life
Hadalpelagic Organisms n Bacteria n Tube Worms n Hadal Amphipod n Snail fish
Deep Adaptation n Water , gelatinous muscles, low protein content- less energy for maintenance
Lifestyles n 3 Basic Lifestyles: • Plankton • Nekton • Benthos
Plankton Floaters or very poor swimmers n Plankton divided into 2 groups: • Phytoplankton – producers, photosynthesizers • Zooplankton – consumers n
Phytoplankton n Must live in the photic zone Most abundant in shallow coastal areas or in upwelling zones The basis of the oceanic food web
Phytoplankton n n Cyanobacteria Diatoms Coccolithophores Dinoflagellates
Zooplankton Foraminifers n Radiolarians n Cnidarians n Combjellies n Arthropods n Larvae n
Zooplankton
Plankton n Meroplankton • Spend only part of their life cycles as plankton • Are the larval stages of organisms that grow to become benthic or nektonic organisms n Holoplankton • Spend their entire life cycles as plankton
Nekton (swimmers) Free swimmers n Maneuver actively in the water column n Found in the water column from surface to ocean floor n
Nekton (swimmers) n 5 Categories: • Reptiles • Mammals • Fish • Arthropods • Mollusks
Nekton (swimmers) n Marine Reptiles: • Turtles • Snakes • Crocodiles • Iguanas
Nekton (swimmers) n Marine Mammals: • Whales • Seals • Otters • Manatees • Dolphins
Nekton (swimmers) n Bony Fish: • Tuna • Barracuda • Eels • Angler Fish
Nekton (swimmers) n Cartilaginous Fish • Sharks • Rays • Skates
Nekton (swimmers) n Marine Arthropods • Shrimp n Mollusks • Squid • Octopi
Benthos (bottom dwellers) Live either on or attached to the bottom n Primarily filter feeders or scavengers n
Benthos (bottom dwellers) n 2 Basic Types: • Sessile - Live attached to the bottom • Vagrant - Able to move about
Benthos (bottom dwellers) n Sessile: • Barnacles • Sponges • Corals • Sea Anemones • Oysters • Clams
Benthos (bottom dwellers) n Vagrant: • Crabs • Sea Stars • Sea Cucumbers • Sea Urchins • Brittle Stars
