1 Ocean Life Zones

2 Foldable Ocean Life Zones
On the folded side, fold over ¾ to 1 inch. Then fold back up and write Ocean Life Zones along with your name and class. Front Cover Fold Both Papers in Half Hamburger Style Ocean Life Zones Cut along dashed lines to create 5 flaps Do NOT cut through the last page.

3 Foldable Ocean Life Zones Intertidal Zone Neritic Zone
Turn your foldable sideways and label the sections Ocean Life Zones Benthic Zone Bathyal Zone Abyssal Zone

4 On the back side of flaps: List 3 types of organisms that live in that particular zone and draw a picture to represent the zone. Look the organisms up, don’t guess at what they look like.

5 Foldable Instructions EVERYTHING IS COLORFUL/NEAT. 1
Foldable Instructions EVERYTHING IS COLORFUL/NEAT! 1. Color should start out light at the top level and then gradually get darker. Make sure titles are legible! 2. Color Info pages: Write in pencil, but your background should be colored and match the background color of Title Tab. 3. Name 3 organisms for each zone and draw a picture of each on the back side of the tab (flap). The entire foldable must be labeled and colored. You will be graded on completion and neatness!

6 1. Intertidal Zone Between high and low tide lines Changes a lot between water and dry land = Difficult for animals and plants to survive because they must be able to live outside of water To avoid being washed out to sea, organisms (plants and animals) must attach themselves to the ground . Put organisms on the last flap and draw pictures for each.

7 2. Neritic Zone Plenty of sunlight Low water pressure
Constant temperature LOTS of organisms live here! Put organisms on the last flap and draw pictures for each.

8 3. Benthic Zone The benthic zone is the bottom of the water. Benthos refers to animals living in this zone (both on and near the sea floor). The benthic zone of the ocean has varied characteristics. There are mountains, trenches, volcanoes, flat muddy areas, sandy areas and rocky areas. There is a wide variety of life that makes its home on the ocean floor. Some organisms live in the mud, some crawl or swim along the bottom and some anchor themselves to the ocean floor. Put organisms on the last flap and draw pictures for each.

9 4. Bathyal Zone Creatures such as this brittlestar, squid, and hatchetfish inhabit the bathyal zone, or mid-depths, between 200–2,000 m (660–6,600 ft). Some sunlight penetrates the upper bathyal zone down to about 1,000 m (3,300 ft). Here the water temperature may be about 5°C (41°F). No light reaches the dark zone beyond, where temperatures fall to -2°C (28°F). Put organisms on the last flap and draw pictures for each.

10 5. Abyssal Zone 5. Abyssal Zone (midnight zone)
NO sunlight reaches this zone Some animals produce their own light Little food is available Very high water pressure Water temperature is very low/cold Put organisms on the last flap and draw pictures for each.

11 Organisms of Each Ocean Life Zone
Intertidal = hermit crab, sea star, mussels, sea urchin, barnacles Neritic = Loggerhead sea turtle, mackerel, cod, kelp, Bottlenose dolphin Benthic = sea urchins, sea cucumbers, crustaceans (shrimp, crab), squid, octopus Bathyal = jellies, and crustaceans. Sperm whales can dive down into this zone when hunting giant squid. Abyssal = Deep Sea Anglerfish, Giant Squid, Tripod Fish, Black Swallower
