Now lets take another look at all the oceans! You will have to identify them next!
Now that you know all the major oceans, we are going to look at the zones of the ocean!

Twilight Zone • 700-3,300 feet • Located below the sunlit zone • Only dim light reaches here • No plants grow here • Animals that live here include jellyfish, octopus, and squid.
Midnight Zone • 3,300-13,000 feet • Receives no sunlight • Some animals that live here are the viperfish and angelfish.
