Low water pressure
Well-oxygenated water
Receives sunlight
Nice stable temperature
Stable salt levels/amounts
Home to many species of marine animals

Sea Grass
Sea Turtles
Most common form of plant life in the ocean
Base of aquatic food webs

Coral Reefs
Surface Zone
Warm top layer of the ocean
Extends 400m below sea level
Mixes heated water with cooler water
Where most currents, winds, and waves occur
Sharks, plankton, tropical fish etc. live there
Small teeth
Deep Zone
Starts at depths of about 800 m below the surface
Bottom layer of the ocean
Temperature ranges from 1-3 degrees Celsius
