Photosynthetic Bacteria and Algae Coral Tuna Fish Butterfly Fish Angel Fish

8 Open-Ocean Zone Lays beyond the continental shelf
Only a small part receives sunlight Deepest, darkest part of the ocean

9 Zones in the Open-Ocean
Surface Zone Receives Sunlight Mild Temperature Transition Zone Change in Temperature Deep Zone No Light Cold Temperature Extreme Water Pressure

10 Marine Life: Open-Ocean Zone
Surface Zone: Zooplankton, Krill Transition Zone: Squid, Shrimp, Prawn Deep Zone: Anglerfish, Viperfish, Vampire Squid, Black Dragonfish
