Ocean Life Zones

Ocean Life Zones
2
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

2. Neritic Zone

• Plenty of sunlight
• Low water pressure
• Constant temperature
• LOTS of organisms live here!

3. Pelagic Zone (sunlight zone)

• Means open sea (Greek pelagos)
• Water is deeper here
• At the surface, there is lots of light
• Down below, the water gets colder and the water
  pressure increases

5
4. Bathyal Zone
4. Bathyal Zone (twilight zone)

• Below the pelagic zone
• At the bottom of this zone, there is no sunlight
• There are no plants that grow ?
• Harder for animals to live here

6
5. Abyssal Zone (midnight zone)
5. Abyssal 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
