Shark's habitat can refer to two different environments. The first is the OCEAN, which is the natural habitat of most species of sharks. Sharks are found in all oceans around the world and can live in depths of up to 3, 000 meters. The second habitat for sharks is a pool hall, which is an artificial environment created by humans. Pool halls are usually filled with water and contain various types of fish, including sharks. Sharks in these environments are usually kept as pets or for entertainment purposes.
