Deep Sea World is a popular aquarium located in North Queensferry, Fife, Scotland. It was opened in 1995 and is Scotland's national aquarium. It is one of the largest aquariums in the UK and features a variety of marine life, including sharks, rays, seals, sea turtles, and octopuses.

The aquarium is designed to take visitors on a journey through the world's oceans, starting with the Scottish coast and moving through the Atlantic Ocean, the Amazon rainforest, the Pacific Ocean, and the Red Sea. Visitors can walk through a 112-meter long underwater tunnel to see the marine life up close, including the largest collection of sharks in Scotland.

In addition to its exhibits, the Deep Sea World also offers a range of educational and interactive experiences, including talks, feeding sessions, and behind-the-scenes tours. Visitors can also take part in diving experiences and swim with sharks or seals.

The Deep Sea World is committed to marine conservation and research and is involved in a number of initiatives to protect and conserve marine life. It has a strong focus on sustainability and has won a number of awards for its efforts to reduce its environmental impact.
