An oceanarium is a large facility that displays marine life in a controlled environment. It typically features aquariums, exhibits, and sometimes interactive experiences that allow visitors to learn about various ocean species. Oceanariums aim to educate the public about marine ecosystems and the importance of ocean conservation. Many oceanariums also participate in research and conservation efforts, helping to protect endangered species and restore marine habitats. They often house a variety of marine animals, including fish, sharks, turtles, and coral, providing a glimpse into the diverse life found in the world's oceans.
