Orcas live in the all of the colder oceans, specifically near countries like Norway.

This particular ecosystem is in the sea and includes many oceanic plants and animals like seaweed, starfish and shark. Because the habitat is the ocean, the color of the sea is blue and green, and the rocks are sometimes worn away by the waves. In addition, there are many plastic bags and other pollutants in the ocean. 

​Orcas generally live in cold water and need seawater temperatures below 10 degrees Celsius to survive.

When orcas sleep, they typically stay close to the surface, swimming slowly and steadily with one eye open and one eye closed.
