The ocean's surface is teeming with creatures that live in water but need sunlight to survive.
- The sunlight zone is the area between 0m and 200m beneath the surface of the sea and is home to endless quantities of life.
- The sunlight zone is where microscopic organisms are able to convert the Sun's energy through photosynthesis.
- Sea mounds are underwater mountains that offer some shelter to small animals from predators.
- At depths greater than 200m, the Sun's light does not penetrate and few organisms can survive.
From above, the open ocean resembles a barren, lifeless, never-ending landscape.
But within the ocean's surface layer lie endless quantities of life.
This is the epipelagic zone, or sunlight zone.
Depth: 0m to 200m
Temperature: -2°C to 40°C
Within the sunlight zone, microscopic organisms such as plankton and algae can convert the ...
